I have an ongoing problem keeping any sps
corals in my 72 gallon tank. I've tried many different types (birdsnest, various acros) and they all end up half dead and then I move them to my other 40 gallon tank and they grow like nuts.
I have a T5HO lighting fixture on the 72 and I always place the sps
corals up towards the top of the tank on some lr
. I'm very good about 20% pwc
every week on both tanks. After a week or so they start to go downhill - loosing color and parts dieing off. If they haven't completely died off I'll move them to the other tank (mh
lighting). I have tons of flow in that smaller tank and obviously the more lighting.
After moving the corals they really seem to take off after 2-3 weeks.
I've tried to figure out why I can't keep any sps
corals in my larger tank and I've come to the assumption that I don't have enough flow in the tank to keep them? Does that seem likely? If so, do you think I could get some extra flow going in just a small area of that tank?
I've checked the water and they both test very similar with a small difference in CA
.....but nothing too wild.
What do you think/suggest?
