Firstly another equipment change to report. I finally decided to change out the Beamswork EVO refugium light for a Kessil H80 Tuna flora. I had been considering replacing it for quite a while now, not because I was unhappy with the light but because the metal stand was rusting in all four corners where it sits on the top of the refugium. I'm not sure if this has caused any metal contamination in the tank yet or not but I wasn't happy with the situation so it had to go. The reason I opted for the Kessil is because it's pretty much the only light that I could find small enough to fit over the refugium, everything else was either too big/long and would have caused a huge light overspill issue or excess heat in the small sump area. To combat at least some of the light spill produced by the H80 I have added a small piece of black acrylic sheet between it and rest of the sump. The red light is something that does take a bit of getting used to but if the macro algae grows well under it then I'm happy, time will tell.
Now for a Fauna Marin Skimbreeze update. The FM media lasted two and a half weeks before needing to be replaced, about the same amount of time as the most recent ATI 1l disposable unit. I'm not that keen on the design of this reactor itself as air is preferentially pulled from the side the outlet tube sits (as can be seen in the photo below). So when changing out the reactor some media is still unused. I think I will try rotating the cylinder next time to see if I can reduce the problem. To refill the reactor I used the Spherasorb media, it looks exactly the same as the FM stuff but costs a lot less.
As for the livestock well everything is ticking along. Acropora growth is slow to nonexistent thanks to the red bugs but at least they are not dying. The exception to this is the A. hyacinthus which seems fine (with a rather odd growth shape it must be said), I've accidentally fragged it with the algae magnet a couple of times now because it's growing too close to the front glass.
The Utter chaos zoanthids are becoming annoying as they keep detaching and floating around the tank ending up in spots where I don't want them in or sucked on to the powerheads. Since I don't have anywhere to place frags (and hate the look of frag racks in the DT) I've chucked the loose ones I've found so far.
The sun coral is still releasing planulae and I keep finding baby polyps popping all over the tank. The more I look the more I can spot, they've even settled out on the clam shell. The larvae are fascinating to watch, tiny orange tear shaped blobs that wiggle around the tank until they find somewhere to settle out. It's very cool!
As for the Balanophyllia now living down in the sump, I can't decide if it's doing better or worse. There is one thing though, I happened to knock it over whilst trying to feed it and when I set it straight again I noticed it has some tentacles poking out the back, my initial response was Oh ****! Aiptasia!! But on closer inspection it actually looks like a baby Balano bud. I'm not sure if this a good sign or a bad one? Is it failing so badly that it's sending out buds as a last ditch attempt to survive?? I surely hope not.
I'll sign off with a few photos.
And finally a FTS..
Not much new to report really, everything seems to be ticking along and there have been no new additions.
I harvested a load of macro algae from the refugium as the upper half was a completely solid mass. I think I might have been a bit over zealous with my pruning as the algae growth seems to have stalled somewhat since then. A knock on effect being that the nutrient levels within the tank have risen slightly. On the 9th January phosphate tested at around 0.046ppm and nitrate 0.35ppm using the Elos low range kits. When I tested again on the 10th January the phosphate level had crept up to 0.08ppm and nitrate to 1ppm. Hopefully once the algae growth picks up again the levels will stabilise as I don't really want the phosphate level to get any higher. I must get into the habit of harvesting smaller amounts of algae on a more regular basis.
I've also been chasing the male pintail wrasse round in the hopes of capturing a decent photo of him displaying to the female but boy, he's really fast! I have multiple shots of just his tail or the rear half of his body, lol. I am very persistent though, thank goodness for digital cameras or I would have probably given up by now.
I finally relented and moved the Balanophyllia to the sump, it was on the fast track to coral heaven if I left it in the DT thanks to the Pintail's attentions. It's so much easier to feed down there now, especially during the day as the refugium is reverse lit so it's nice and dark. The good news is whilst the flesh on one side has receded quite badly due to the earlier infection it doesn't appear to be getting any worse and it's certainly happy to start eating again. It's a pale shadow of what it once was, the photo below shows how far the tentacles currently expand (and the receded skeleton). I hope it improves and opens up fully again.
The green tentacled corallimorph was looking a little more extended than I usually see it during the day so I whipped out the camera for a quick snap of that too (with flash). It looks like an anemone (and is commonly called a ball anemone) but actually is a part of the mushroom family. It hitchhiked into my tank on a small piece of zoanthid rock and doesn't appear to have spread much in 8 months time, mind you neither have the zoas either, lol. I think it actually looks rather attractive.
I'll sign off with another short video. It's not much different than the last one I posted tbh but hopefully still enjoyable to watch.
When the lights switch off above the display tank there's still plenty of action to watch down below in the refugium.
My tank is exactly a year old today! Wow, where has the time flown to? I've been a bit lax with the updates recently so there's lots to catch up on.
First lets get the bad news out of the way. I'm afraid that I've lost the lovely Tridacna maxima clam, it simply never thrived in my tank. Before adding it I carefully checked the shell looking for any nasty hitchhikers but I never found any. I must have missed some (or their eggs at least) as I started to notice some pyramid snails feeding on my precious Trochus and Turbo snails. Nooo! I checked the clam regularly at night with a flash light but never found any of the little devils feasting on it. After two and a half months it finally it became clear that the clam was doomed so I decided to remove it before pollution became an issue. I checked it over again when it was out of the tank and still couldn't find any pyramid snails on it. These guys are so small and clearly hide really well! Later on three teeny tiny ones did emerge from inside of the clam, it's hard to imagine that just three could have any impact on an animal so much larger than they but clearly over time they do. Unless of course the maxima was suffering from something else too?
At this point there's not much I can do about the pyramid snails, I am removing any that I see every day and I've become quite adept at spotting them now. On average I remove about 10 per day. The wrasse are sadly not eating them, come on guys I could really do with a helping hand here, sheesh earn your keep why don't you!! At least I haven't lost any of the snails yet and my original Tridacna crocea clam seems to be doing fine, it's laying down new shell so I take that to be a good sign for now.
The other blip on my reefing horizon is the Balanophyllia. It just doesn't look as good as it once did and I can't work out why. Am I feeding it too much or not feeding it enough? I had been offering it a piece of food once per day (at night), generally PE mysis, clam, Krill or lancefish, perhaps that wasn't enough to sustain it? So I decided to up the feedings to multiple times per day (anywhere between three up to a maximum of five a day) but this seemed to make no difference at all (in fact the coral looked a little worse) so now I'm trying less food. It's really frustrating because the sun coral is looking fantastic on a single feed per day.
Apart from the above everything else seems to be doing OK. The fish are all good, Rei the Yellow wrasse eats like a horse and is noticeably bigger. The best news is that my Tomiyamichthys nudus gobies have finally paired up with the Red Spotted pistol shrimp so I get to see them all much more now. The male goby still goes MIA every now and again but always resurfaces at some point. The gobies and pistol shrimp do not naturally associate together in the wild but I suspect they have done so in my tank because there are simply no other alternatives.
The corals are getting bigger and some are starting to get close to each other already, war is on the horizon I expect.
The zoanthids are spreading nicely especially the Utter Chaos, these are reproducing at a phenomenal rate and unfortunately over taking some of the original slower growing morphs. Whatever was afflicting the Red Tuxedo zoanthids seems to have subsided and I've not lost any more recently, I hope that's the end of that.
After a bit of a slow start the algae in the refugium has really got going now and the amount of life in there is incredible. It's amphipod, mysis shrimp and brittlestar heaven! Charlie the hitchhiking crab is alive and kicking and still growing. She was such a tiny thing when I first noticed her in the DT hanging out in the Seriatopora, now she's huge in comparison.
Life in the refugium.
Whenever I harvest any algae, I spend the following 30 minutes rescuing brittlestars from amongst the fronds. Well I can't just throw them out can I? It's easy to see how they are reproducing by division.
My first canister of ATI Carbo EX came to the end of its life in September, it lasted just over 3 months which I don't think is too bad. I have decided to continue with the CO2 scrubbing and have replaced it with a fresh cartridge.
Last week to celebrate the fact that the tank was approaching its first birthday I decided that some new additions were required. There was a gap (left by the T. maxima clam) that was just crying out to be filled. OK it didn't really need to be filled but what can I say, any excuse to shop for new corals.
I decided another encrusting Montipora sp. would do nicely and since it was likely to be the last addition (never say never tho) I wanted something special. I decided the Beach Bum (what a name!!) Montipora would contrast nicely with the three that I currently have. Since I was mail ordering from a fellow reefer I found I couldn't just buy the one coral so I ended up with frags of Hawkins Echinata (Acropora echinata) and a Sunrise Goniopora too. My name is Lisa and I'm a coral addict, lol!
Here they are on the sand awaiting fixing (squeezing!) in place.
Phew that was a marathon (are you still with me?) before I sign off I'll add a few more updated photos. After all who doesn't love a bit of eye candy?!
Charlie climbed to the top of the refugium to say hello to me this morning. I discovered her sitting on top of the thick mat of algae. Oh my, she's grown a lot! So is clearly finding enough to eat down there. :o)
On the 18th April I relocated Charlie (or is it Charlize?) the hitchhiking crab from the DT to the refugium. After almost 4 weeks of no-show, today I discovered him (her?) alive and well in the jungle. I am chuffed, what a survivor!
Also I've also been playing around with a new macro lens, starting with some of the easier corals to capture.
Never in a million years did I think that it'd be easy to catch and remove my hitchhiking crab but boy how very wrong I was. My deluxe homemade crab trap actually worked first time! I propped an empty glass spice jar up against the top rock where the crab lived and baited it with some mysis shrimp just after lights out. I honestly felt that the jar was a little too tall for the job and it would never catch anything but to my very great surprise it did. I checked back on the tank after just an hour and was gobsmacked to discover the crab sitting in the jar. It's so great when a plan comes together without any blood being shed (and doesn't cost anything, lol).
With clearer photos I'm now confident that the crab is indeed Chlorodiella nigra. Please refer to the link below for comparitive purposes.
Of course I couldn't bring myself to kill the little guy, after all he had done no wrong, simply knocked a frag off the rock which was probably my fault for not fixing it down securely enough. The biggest issue for me was the fact that he'd set up home right next to my clam and whilst this species is reported to mainly eat algae I didn't want to take the risk of the clam being irritated or even worse becoming a crabby snack down the line. So off he went into the refugium where hopefully he'll be content with an endless supply of algae (and pods?) to munch on.
Yesterday I (along with the assistance of my better half) installed my long awaited shiny new GHL Doser 2 SA pump. No more manual dosing for me, yay! This piece of equipment is seriously snazzy, it feels solid and it just looks so very, very cool. I almost wish I'd got it sitting in full view; the light show it gives off is seriously impressive. It flashes violet, red, yellow, green, white or blue depending on its status. It reminds me of my teenage disco days lol! My only disappointment with the unit so far was the lack of a UK plug. Why?! The Mitras light has one so why not the doser too?? Very annoying indeed.
The initial set-up was straightforward and I especially enjoyed calibrating the pump heads, it made me feel like I was back in the lab again. Programming the dosing schedule through the GHL Control Centre was easy too. However where we fell down was trying to connect the doser to our home wifi network and then on to the myGHL Cloud. The disco light was supposed to turn blue when connected but it resolutely stayed blinking white no matter how much I shouted and pleaded with it. We did get there in the end after we double, triple and quadruple checked the instruction manual and all the data required (IP address/password info etc). I'm not sure I would have been able to sort that bit by myself to be honest. Good job my other half is useful with a computer.
The doser and dosing containers are situated in the cabinet next to the tank along with the ATU tank. Presently I'm using it to dose Tropic Marin balling salts (A, B & C). One pump head is currently redundant but I'm fairly sure I'll find something extra to dose at a later date. The liquids are dripped into the return chamber of the sump. Since space is severely limited inside the cabinet (with the refugium tank in place) I swapped out the Reefloat Sensor sump mount for the new Reefer mod. This was very easy to do, rather like changing a plug. Now the dosing tube holder sits where the sensor sump mount used to be, all very neat and tidy, well sort of if you ignore the spaghetti junction of tubing and power leads down there.
I always love to check out what's happening is the sump/refugium areas. The refugium whilst not particularly successful at growing lush macro algae, is at least good for cultivating amphipods and has a healthy number of spirorbid worms growing on the glass (as does the back wall of the DT to be honest). I was pleased to discover last week that at least one of the three mini brittlestars that I introduced as part of a refugium pack in December is still alive and and much bigger too. It's the first time I've seen one since the week of introduction (8th December 2016). Interestingly I discovered a sycon sponge has settled in the sump on one of the siporax rings, I think this is a good thing rather than bad.
It's four months since this little tank was set up and all seems to be going really well. Almost a bit too well actually, I'm expecting something to go wrong at any moment, it's usually the way. I'm keeping a close eye on the water parameters now that I have added a few more corals. In the past I have really struggled to keep the alkalinity and calcium levels at appropriate levels even with the use of a calcium reactor and kalkstirrer. As soon as it was pumped in it was sucked up by the corals and clams. This time round I'm hoping to maintain good levels with careful dosing. The parameters today were:
The above were tested using a refractometer, Salifert test kits and a Hanna pocket checker for the phosphate. I'm fairly sure that my phosphate level is not really zero but it must be pretty low and there is very little in the way of nuisance algae growth in the tank apart from a bit of furriness on the rocks. I do not know what the furriness is but it doesn't look too unsightly and stays short. In any case there seems to be less of it now. The macro algae growth in the refugium has been disappointing to date, considering the lack of nutrients I suppose it's not entirely surprising. As long as the reason is not down to a lack of flow or lighting, time will tell, I can't imagine this situation will last for long. I've started dosing a small amount of Reef Roids and KZ Sponge Power recently so they may affect the levels in the future.
You'd think that over 4 months I'd de familiar with all the livestock in my tank, well no actually. A couple of days ago I noticed that the Seriatopora had retracted its polyps and on closer inspection I discovered a small crab sitting at it's base. Where on earth had he suddenly popped up from?? I highly doubt that he came in on any of the SPS frags as they are too small to conceal a crab, I suppose it could have hitched a ride in on the zoanthid rock but the most likely explanation was that it was hidden in the live rock when it was first added. It doesn't look like it's chowing down on coral flesh (at the moment, heh!) so I'll leave it be for the time being and watch and wait. I hope it behaves itself or we'll be having some fun and games with extrication later on.
