I let the tank and myself have a breather for a week following 'clamgate'. Clive the clam appears to be fine after the incident and I'm pleased to report that nothing succumbed to an excess of clam ‘protein'. Then I transferred over my two remaining Acropora (gomezi and hyacinthus). I'd been putting off moving these because as we all know SPS can be tricky in new systems but it had to be done and if they didn't make it that'll be that. The A. gomezi was super easy because it's a tiny frag on a frag plug but the A. hyacinthus had grown rather large. I tried my best to frag it off the rock in one complete piece but, yeah that didn't happen. It broke into three, I was going to keep the two largest but in the end I opted to add a single bit only (easier to fix down). Those who followed my old thread may remember that the Reefer 170 had an issue with red bugs. I hadn't seen any of the little red devils for ages but that doesn’t mean that they were all gone, I can only hope. I dipped both frags in Reef Primer and checked them quite thoroughly before they were transferred.
Now we get to the big one. On the 26th April I decided to complete the tank transfer and shut the Reefer down. Prior to this I made one last concerted effort to catch Rei the yellow wrasse and Spike firefish but Rei would only poke his head briefly into the trap and Spike avoided it entirely so it was simply a no go. We did try catching the Spike using nets and acrylic baffles, much chaos ensued with the tiny fish outwitting us every time.
The strip down progressed pretty much as planned with no disasters to speak of, I found it quite stressful nonetheless. We emptied out the water and rocks in stages. The corals that I wanted to keep were cut off and placed in one bucket with the remaining rocks/corals going into another. Spike the firefish was cornered with a net and safely removed. Ming the Pom pom crab was discovered clinging to the underside of a rock. Finally we were left with a tank containing a little water, one last piece of rock and sand. With my breath held, the rock was lifted out revealing Al the pistol shrimp and Flash his Whitecap goby partner hiding underneath. Phew! A careful bit of sand exploration was required to flush out Rei the yellow wrasse. Swipes the porcelain crab was MIA at that point so we had to carefully go back and examine every bit of rock again placing them one by one back into the Reefer as we went. Finally we discovered her hidden in a hole in one of the base rocks. That was pretty much it except for one last thing of note, I discovered a rather scary number of Aiptasia living in the overflow weir along with half a dozen baby sun corals.
Following the transfer Rei the yellow wrasse hid in the sand for a whole 10 days before finally deciding to make an appearance. I honestly thought he’d died from stress or something. Everything else made it through OK which I’m relieved about. The fish were naturally pretty freaked out however so I didn’t take any photos for ages.
The Acros are still alive and growing but have lost colour which is probably down to the poor nutrient situation. There have been a number of reports circulating recently that TMC eco reef rock leaches phosphate and silicates but apart from a brief spike of phosphate during the cycle that hasn’t been my experience at all. Nitrate and phosphate have been consistently registering as zero on my test kits (Salifert and Hanna respectively). In the old days this wouldn’t have bothered me much but the internet has taught me to fear the dreaded D word. For a while I saw a little growth of what looked like some brown algae on the rocks but when viewed along the length of the tank with natural lighting behind was in fact green hair algae. There must have been some nutrients knocking about somewhere to fuel the growth. This algae started to become a little more pronounced so I decided the CUC needed a tiny boost. Two weeks and 6 small Trochus snails later most of this algae was gone, I felt quite pleased with myself. However the removal of the hair algae shifted the balance somehow and combined with a lack of nutrients I began to see the appearance of dinoflagellates on some of my gorgonians. Normally I would take a watch and wait approach but it’s hard not be affected by some of the algae horror stories I have read online. I dusted off the microscope and identified the species as Ostreopsis, fearing a full blown infestation along with the death of my beloved snails I decided action was required in the form of nitrate dosing. I had already been feeding quite heavily to that point including Reef roids and phytoplankton but it didn’t seem to have made any measurable difference. It felt wrong to be actually dosing nitrate! I began with a laughably tiny amount (0.5ml of Brightwell’s NeoNitro per day, 12.6ml will raise my tank volume by 1ppm so 0.5ml was nothing lol). After 6 weeks I gradually increased the dose to 4ml per day, during this time the dino growth increased slightly, mainly evident on the gorgonians, but never turned into the major disaster I feared. The gorgonians still had their polyps extended and the snails seemed fine too. I continued my weekly water change regimen using the opportunity to siphon as much of the dinos as possible every time (not recommended I know but I like to perform water changes).
When the tank was 4 months old I sent off the first ICP sample. I discovered elevated levels of Cobalt and Aluminium. I have no idea where they have come from, leeching from the rock maybe? The nitrate level was 0.02mg/l, phosphate was 0.03mg/l and silicate was 66ug/l. Iodine was a bit low as expected (and some other elements low as per usual).
Finally after 7 weeks of dosing nitrate I started to register 1ppm on the Salifert kit, incredibly the dinos started to recede! This might have been a coincidence of course and nothing at all to do with the nitrate level but either way I am happy.
I am curious to know why I’m not registering a release of phosphate and/or silicate from the TMC eco reef rock. Perhaps the corals are soaking up the nutrients as they are released, the gorgonians are growing very fast. Or maybe the rock is hatching a plan to trip me up later on down the road.
Coral warfare/shading is a becoming more and more of an issue as you would expect for any reef tank approaching 3 years of age. Well perhaps not if the tank had been sensibly/lightly stocked but I guess this hasn't happened. Common sense seems to fly out of the window where myself and reef tanks are concerned.
Most of what I'm going to post is kind of good really. Generally the corals are growing well but there are some that are losing the battle for survival.
The Stylophora needs regular trimming to prevent it from growing up to and touching the left hand glass wall. Its base continues to expand and kills off areas of contact with two neighbouring Montipora as it goes. It has also (along with the Pinnigorgia gorgonian) almost completely shaded out the Beach Bum Montipora. The Beach bum is fading away and there is nothing I can do about it, it's pretty much impossible to relocate. I try not to dwell on this fact too much, it's too painful. Big mistake. Big. HUGE!
I removed most of the green plating Montipora a while ago but it's making a comeback and shading the corals below again. I should never have introduced a frag of this in the first place, I just knew it would end up causing issues in a small tank but it was free and I just couldn't throw it away. On the plus side I must admit it is a lovely vibrant green colour.
The encrusting 'Superman' Montipora is possibly worse than the green plating Monti, I am definitely in need of some marine Kryptonite for this particular coral. At one point it grew up along one side of the clam till the Crocea decided enough was enough and forced its shell open wide enough to snap a good chunk of the the Montipora right off. The Superman Monti also kills any Seriatopora hysterix it touches and has encrusted over nearby Acropora like they were nothing but bare rock. Interestingly it has actually run out of rock space to the rear and has started growing out in a thick plate like formation instead.
I grudgingly accepted the loss of the purple tipped Acro frags to the Superman as they were not thriving anyway (due to the presence of red bugs) but it was harder to take the potential loss of the Acropora gomezi. Despite the parasitic bugs, the A. gomezi still showed nice colouration, not what it should look like under normal conditions but still nice. For months I gritted my teeth and watched this Acro be overgrown, but right at the last minute I decided to frag off the remaining two branch tips. I fixed both of them to the same frag tile and plonked it on the sand. A quick survey with the magnifying glass showed me that the tiny A. gomezi frags are still providing a home/food to the red bugs. I could remove and dip them (repeatedly if needed) but if the bugs are present elsewhere in the system then they will just become reinfested again. The frags have encrusted on to the tile but that's about all they've done at this point. One of the branch tips had a close encounter with the Scolymia thanks to a hermit crab, and got stripped. It's almost recovered bar for a tiny bit of algae covered skeleton at the very end. You can see one red bug highlighted but the arrow in the photo below.
The only other Acropora species remaining in the tank is A. hyacinthus (aka Red Planet), I have yet to discover any red bugs on it but that doesn't mean there aren't any lurking out of sight. Interestingly this Acro has been looking better recently colourwise, it's actually starting to look red once more, well pink at the very least.
The Scolymia continues to look good. It needs to be moved in the not too distant future as the Favia behind is creeping ever closer. I can't afford for those two to meet! Knowing my luck the (much) more expensive coral would be the loser if they clashed.
The Favia has completely overrun the Cyphastrea that used to grow to the right of it and continues to bubble up towards the Acanthastrea to the left. There's been no full on attack as of yet.
The Acanthastrea are surviving but not really thriving. I know that they prefer lower lighting conditions but the plating Montipora above is shading them too much at present. I have been trying to feed them to try and make up for it but 9 times out of 10 Rei the Yellow wrasse steals the food.
The Oxypora keeps expanding ever so slowly, it is also somewhat lacking in light these days.
The Utter Chaos zoanthids are a complete nightmare. They grow so fast and don't seem to be bothered by anything (at least nothing they have encountered in the tank so far). SPS corals are fair game, they just reach up shade out an area of coral until the flesh recedes and then they colonise the dead skeleton. I'm sure that this is a familiar story to many other reef keepers. Having never kept zoas before this is a new one on me. They have grown up the side of the clam and were beginning to reach over and shade the mantle before I decided to scrape them off. A temporary fix as they are encrusting again.
To be fair it's just the Utter Chaos zoanthids that are causing a headache, the rest are much slower growing (aside from growing out onto the sand which is making it hard for Lurch the conch to navigate round the tank).
The Heliofungia has grown to a lovely size but is really squashed up in the front left hand corner of the tank. It remains attached to the small rock and so cannot move around. This is possibly a good thing as I'm sure there would be carnage if it could scoot along the sand and relocate itself. It expanded so much that it was stinging the orange Dendrophyllia to the right of it.
The Lobophyllia has been doing OK, it's really slow growing but since it's tucked away at the side of the tank with not great lighting then that's not exactly surprising. It started off with one head and now almost has three.
Unfortunately one night it suddenly launched an all out attack on the Black sun coral. Before now it had been almost completely overgrown by the Utter Chao zoanthids and not retaliated but clearly the threat posed by the Black sun was a different matter. It stripped three branches of the sun overnight.
Since the orange Dendrophyllia and black sun both needed moving, plus I (still) had the Balanophyllia sitting in the sump I decided space needed to be made for them elsewhere. In the end I pulled out 100+ Utter Chaos zoas, clipped a few branches of A. hyacinthus and removed all of Seriatpora hystrix. The Seri broke into pieces during removal and I decided to keep just a single piece and reposition it a little higher up. This left a space big enough to just about squeeze in the sun corals, now I have quite a nice little cluster of NPS corals on the right hand side of the tank.
After spending over a year and a half in the sump the Balanophyllia is finally back in the DT once more and it's looking good, I don't know why I struggled with it so much. I wonder if perhaps it had some sort of infection that caused the flesh to recede before. It's good to see it back to full health (fingers crossed). I'm also thrilled that the accompanying hitchhiker bivalve is still alive too, I have no idea what that is eating but it must be filtering out enough as it has grown larger since introduction.
The yellow Dendrophyllia remains in place next to the Heliofungia, it has encrusted onto the rock work so I'm not going to mess with it. Eventually I expect it too will be stung but that's a problem for the future. In just over a year this Dendro has increased from 3 to 15 separate heads with another forming. Such a lovely looking coral.
The Pinnigorgia gorgonian goes from strength to strength, it grows so fast and always fully extends its polyps. I have cut off a number of branches of it already and need to trim it some more. The Muricea and Plexaurella gorgonians are much slower growing tucked away at the back of the tank.
That's it for now, I will post an updated full tank shot in a few days' time.
I've been really pleased with the progression of the tank recently, the fish seem settled with no argy-bargy between them, coral colouration continues to improve with each week and things are generally looking healthy. I hope by saying that I've not just jinxed everything now.
As a consequence I have been on the look out for a few more corals to add a bit of extra interest to the tank. It's proven hard to source the last few bits from my wish list as they don't seem to be readily available or the pieces I've come across in the shops are just too big to squeeze in my tank. Regular readers (if there are any out there? Ha ha!) will know that I've been trying to stick to small frags so that I can enjoy watching them 'grow in', plus buying aquacultured corals has always got to be a good thing, right? After 7 months of keeping my eye out I resorted to shopping online (my second favourite pastime). I never thought I would actually take the chance of buying corals online but so far my experience of it has been all great with no losses to date.
Yesterday the postman brought me not one, but two packages, it was a very exciting day.
The first package contained 3 corals. A Balanophyllia sp., possibly my new favourite coral. This is non-photosynthetic and will require feeding by hand but it is so very, very pretty. I had originally wanted to source a small colony of sun coral (Tubastrea sp.), as I've kept those in the past and found them easy to care for but have not seen any for sale, They used to be regularly available but not any more it seems. Anyway this species is very similar (and fits in the small size theme) so I decided to give it a go. My research has suggested that they only extend their feeding tentacles at night but this one seems happy to open up no matter whatever the time of day which is wonderful, more time for me to admire it! As a bonus there is a mussel attached at the base, although I haven't ascertained if it's still living or not. I do hope so but keeping it that way may prove difficult as it's a filter feeder.
Check out all those nematocysts!
Then came a baby plate coral, now I knew that I wanted an LPS coral with swaying tentacles and had originally considered a Euphyllia sp. but I know these can get very large over time so I finally settled on a plate coral. When I saw this baby one available I knew that I wouldn't have a better opportunity to purchase one, it really is tiny measuring just 2cm across when the tentacles are expanded. Normally these corals are free living on sandy or muddy substrates but this one presently has a 'stalk' and when it arrived was glued to a flat frag plug. Unfortunately the frag plug was covered in tiny Aiptasia so it just had to go. The base was duely chopped off along with as much of the original superglue as I dared (and there was a LOT!), then it was fixed it onto a spare piece of rock I had in the sump (I just knew that I'd find a use for that rock eventually, lol!). Now I am hoping that this coral is indeed a long tentacle plate coral, Heliofungia actiniformis and not a very small branch of a torch coral, Euphyllia glabrescens. They do look rather similar when small. I guess time will tell, if it grows and detaches from the base to become free living then it'll be a plate coral, if it develops new branches then it's not!
The final part of this order was a Sunny D zoanthid (plus a baby bud), during transit the polyp had worked itself free of the frag plug so clearly it had been fragged very recently. My first response was one of annoyance but as I hate the look of frag plugs in general it proved fortuitous, it was a simple matter to dab a bit of glue to the base of the polyp and fix it to my live rock. It opened up within a few hours of introduction and is still there today so hopefully it'll survive. I think it's fair to say I'm now a fan of zoanthids, I'm up to 7 different types now, how did that happen?! ;o)
My second online order came all the way from France, how brave was that!! Ever since I added my first gorgonian I knew that I wanted to introduce at least one other species. I had been waiting to purchase the purple frilly gorgonian that Reefworks supply but as it hasn't been available for months I started searching elsewhere. Sadly gorgonians seem to be a bit of an afterthought at most LFS I have visited. The SPS corals are lined up neatly in tanks but the gorgonians seem to be plonked in without any care to their wellbeing at all, most ending up lying on their sides and being stung by something more aggressive resulting in stripped branches or worse. Fortunately for me I discovered Eco-Gorgs, sustainably-produced aquarium sized Carribbean gorgonians, perfect for me and only a few clicks away. OK, admittedly a bit of a journey was required to get them to my tank but worth the chance i thought.
First in my basket was a small frag of Plexaurella sp. and very fluffy looking it is too.
This was followed swiftly by Isis hippuris, though I have to say it doesn't look anything like images of this species online but what do I know?
...and lastly Muricea elongata because it seemed a shame to only order just 2 corals when they were coming so far. This is the only one that has not fully extended all it's polyps yet. I had to leave all 3 gorgonians on the sand for a few hours after acclimation whilst I went out and when I got back this one had been knocked over, typical! There seems to be a bubbling issue with the two branches that had been in contact with the sand. Fingers crossed it will recover in a few days time.
That's it for the time being, I'll try for some better shots of the new corals later on in the week when they've fully settled in and maybe even a new FTS. If you've managed to read all the way to the bottom of this post then top marks, you must be a sucker for punishment!
