We have a 90 gallon tank that's been up and running for almost a year now. We've taken the approach of buying small frags rather than big pieces so that we can enjoy watching them grow. Overall most of our frags have done great. Except torches. Apparently I'm a torch killer because I've tried three times and they've all died within a month. Argh. But otherwise most of our frags have done great and grown like crazy. But we've had three corals, two zoa frags and an octospawn that have died or look like they are dying in the last month. Seeing how everything else in our tank looks great I'm not really inclined to change anything but I'd love to know why these guys went downhill. Some quick specs about our tank.
- 90 gallon plus 20 gallon sump
- 2 Hydra 52's, borrowed a PAR meter from our local reefing club and the highest points of the tank get between 300-400 PAR at the height of the light cycle. Lights come on at 8am and ramp up over a 4 hour period and then start ramping down around 3pm.
- CA 420, ALK 9.2 MAG 1400, PH 8.04, Salinity 1.026
A few pictures of the ones that have died or seem to be in the process of dying. The Zoas basically melted away. The frogspawn has been mostly closed up for the last 3 weeks and hasn't grown much.
A few quick pics of some of the other corals in the tank that are doing great.
I feed the coral a few times a week, I rotate between reef chili, reef roids, and acropower. The only fish in the tank are a pair of ocellaris clownfish and a watchman goby. We used to have a emerald crab but I haven't seen him in almost a month so I'm pretty sure he died. We had him since we got the tank and he was huge so maybe he just died of old age? We have lots of blue legged hermit crabs but I've never seen them bother the coral. I'm wondering if maybe it was too much light for the two zoas that melted away? I slowly built them up to that spot over a period of 2 months and the zoas on the other side of the tank are at almost the same level of PAR and they're doing great.
