Just prior to the skimmer failure I sent off water samples for yet another ICP analysis. The results of which are shown in the link below:
100%! Apparently I have a full house, everything is in balance although to be honest the salinity is a bit higher than I would like. I must try harder. The conductivity probe had drifted out of calibration. The tin contamination is gone at last but I seem to have a reading for iron this time round. The only change between now and the last test is that I have begun to soak the fish food in a vitamin supplement, I wonder if that’s the source? Something (else) to keep an eye on. I still can’t get much of a nitrate reading despite adding a couple more fish and feeding loads. I wonder if running the tank for 5 days without a skimmer has raised it at all?
Moving on to the corals, the warfare continues. The Favia continues to batter the Cyphastrea relentlessly. I thought it might stop once the leading edge was dead but no, the dead area seems to get larger every day. I would move the Cyphastrea if I could but firstly, it's well encrusted, and secondly I have nowhere else to put it.
Two of the Montipora sp. (#2 & 3) are now clashing with Acropora loripes and both are losing. Montipora #2 is also being hammered at the back by the Stylopora.
Despite religious feeding the Balanophyllia has still not been doing so well, It was only after I made the decision to move it that I discovered that it was receding very badly at the back where I couldn’t see. There was a white band of what I assume to be a bacterial infection at the receding edge. I relocated it to the rear of the tank but in hindsight I should probably have placed it in the sump because as soon as the Pintail wrasse were added, feeding it became nigh on impossible. They just kept stealing its food. Fortunately the Sun coral continues to do well and has grown multiple new heads. Feeding it can be a battle with the wrasse but it can be done with a little perseverance.
Moving on to the red bug problem, with no plan of attack they are obviously still present but the Acros seem to be coping with them for the time being. I fully expected the afflicted corals to be failing by now but they still have reasonable polyp extension and colour. I'm sure that they could look better as could their growth rate but at least they are not dead. The watching and waiting continues.
I've indicated some of the red bugs present on the Acropora below with red arrows there are more shown in the shot but you get the general idea.
As for the fish, Edna the Possum wrasse passed her first anniversary in the tank on December 18th and Kylie the Pink-streaked wrasse will have her first anniversary on the 28th January 2018.
A few more photos of the Pintails (Tinker and Belle) and Rei the Yellow wrasse too.
A few other random coral photos. I had hoped to have more shots to share but Christmas preparations got in the way.
Thanks for following my blog, I hope you all have a great Christmas! Hopefully I have more photos to share next week.
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.
For the most part the tank is doing OK. There is very little in the way of nuisance algae, the furry stuff that was coating the rocks seems to be fading away without any intervention on my part. The zoanthids are opening up nicely and looking good, so I think the nudibranch problem is solved. The LPS expand nicely during the day and are always ready to eat whenever they sense food in the tank.
Most of the SPS corals are doing well, showing good growth or at the very least basing out. Colouration however is not great for some of them, I'm hoping that with time and stability the colours will improve. Maybe it's a nutrient issue?
There is one Acropora sp. (#3) that does not look good. I have noticed recently that there appears to be blistering to the flesh. This is a new one on me so I did a bit of searching on the web and others have reported this ailment. Unfortunately no one really knows what causes it. Some say that it's due to an imbalance with the big three, i.e. KH, Ca and Mg but in my case I have those parameters well within recommended levels and they haven't fluctuated much either. The only suspect I can think of at this stage is KZ Sponge Power, I began dosing this on the 11th February (1 drop every other day). It may have nothing to do with the problem but I think I'm going to stop using it for a while and see if the Acro improves.
I nuked the tiny Aiptasia that sneaked into the tank on the clam shell with Aiptasia-X and didn't feel bad about it at all. Now I just have to be vigilant for more Pyramid snails. My list of hitchhikers found in this tank is growing ever longer.
I'm happy to report that the fish are all doing fine. It's been just over a month since I added the Pink Streaked wrasse and I'm thinking that the time might be right to introduce some more soon. This time I definitely want fish that will swim out in the open. I have fish that hug the rockwork, that sit on the sand and one that hides in a hole in the sand, I really need some bold fishies that aren't shy!
A new month and a new FTS. Besides a few new corals not that much has changed really. The Stylophora is showing some nice growth, the Lobophyllia and Acanthastrea look good, the zoanthids are, err, surviving. I think that all the nudibranchs have gone now and the remaining heads are opening up once again, I did lose a few of the orange ones that were on top of the rock, they simply melted away. Too much light/too little light/too much flow/too little flow? Who knows?? To be honest I've never really been that successful with zoas, perhaps the water is too clean? I'm considering feeding some coral foods to see if it helps them at all.
Acro #1 looks the same, it was knocked off the rockwork by a naughty hermit crab and when I stuck it back down it was in a slightly different orientation so it's difficult to tell if there has been any growth or not. Acro #2 has shown a tiny bit of growth and the damaged tips on the lower left-hand branches have regrown. I do think that they have lost a little colour though, another reason to try feeding perhaps, plus the nitrates and phosphates are still undetectable which according to current thinking is not ideal for SPS these days.
Since the Pink Streaked wrasse was added the Nudus gobies and Red Striped goby have moved to the front right of the tank. I get to see a lot more of them now which is really great. The tank has settled down nicely again. I need to relocate the Lobophyllia as Lurch the conch keeps knocking it to the left in his quest to clean the lower rocks. I am also thinking of adding a plating coral to the rock that sits above the pistol shrimp and Whitecap's home (I've seen them again today btw, two days on the trot I think that's a record, lol!) in order to give the entrance to the burrow a bit of shade, I think that will help them to feel more comfortable and hopefully they will become more visible. At the moment the lighting is really too bright for them.
I've been trying to get some shots of the Possum and Pink Streaked wrasse but it's proving difficult as they don't sit still like the gobies do. I will keep trying. Oh and last but not least Crystal the Bruun's cleaner shrimp shed her exoskeleton again last night so she seems fine too.
So my tank seems to have passed the first coral test, all of the frags I introduced 12 days ago are still alive. Phew! The Stylophora is even showing signs of growth. I think it might be time to add a few more at the weekend and maybe even another fish.
The coralline has really started to take off, I'm seeing spots of growth on the pumps and on the back wall too. I am undecided as to whether I should scrape it off for a nice clean look or leave it au naturel. I'll live with it for a while and see how I feel when the coverage increases. Spirorbid worms have also begun to appear in the DT and in the sump too.
The tank parameters as of this morning are:
Specific Gravity 1.026 d SG
Alkalinity 6.85 dKH
Calcium 425 ppm
Magnesium 1270 ppm
Nitrate 0 ppm
Phosphate 0 ppm
I'd like to tweek the KH and Mg up a bit more but those values are not too bad. I am extremely surprised not to have any detectable NO3 or PO4, this is a bit of quandary for me, I don't think I've ever had a tank with no (or low amounts) of NO3/PO4. I guess the Siporax and refugium must doing their thing, it is early days though and stocking is light I so expect that the levels will rise soon. I do have a bit of furry algae growth on the rocks and a film of algae forms on the glass so I know that there must be some nutrients hidden in there even if the tests say different.
Happy New Year everyone, I hope you all enjoyed the festivities.
I am pleased to report that my tank has corals in it at last! I took absolutely ages at the LFS deciding what to buy. I'm still not sure if I have made the right choices but the deed is done now so I'll have live with the consequences. My criteria for selection were small pieces/frags only and easy(ish) corals to care for. So I am now the proud owner of a small rock with a scattering of zoanthids, a frag of Stylophora pistillata and a frag of Acanthastrea sp. At the insistence of my son I also came home with a couple of micro hermits. As far as my kids are concerned, crabs are absolutely awesome and corals are just blah! I did however, put my foot down at the suggestion of buying a clam at this point. As much as I would love one I think the tank is too young and unstable at the moment.
With regards to the resident stock, the squat lobster is still MIA so it's looking like he's probably gone up to the great reef in the sky, I doubt that I'll be getting another if that is the case. He will be my first loss and will be sorely missed. The Scaleless Shrimpgobies are spending more and more of their time hidden in their cave and have become very protective of it too. Any hermits that venture too close are immediately attacked. Neither goby has fed today in fact I have only seen one of them (not sure which one) a couple of times this afternoon. I do hope they are OK. Edna the possum wrasse has become a bit more confident and I can feed her directly from a pipette, she still quite shy and prefers to swim close to the rockwork and hang out under overhangs though. Candy the Red Striped goby is going strong and seems unfazed by anything at all, food is definitely on top of her list of priorities.
