I'm experiencing reduced polyp extensions on FEW of my acros. Tort, abro, gomezi, echinata are few, but rest of my sps has got great extensions. I thought it could have been my water parameters, but I check my water religiously.
CA - 440 Pho - 0
PH - 8.2 Mg - 1300
Alk - 8.4 Temp - 80
Only thing it might be is my tank is becoming very poor in nutrient lately. Could it be b/c of lack of nutrient in water, so some of my corals are less depended on PE and more relying on light only? Nutrient poor environment could result in corals not relying capturing food in the water column during the day, but rather photosynthesis. That's why we only see PE only on night on some of our sps.
It's just my theory, and I'm glad someone mentioned this b/c same thing is happening to my friends tank here in Houston. Check out the pictures of my tort. I'm getting growth, so I don't think the corals are stressed.
Does this happen when you go into phase 2 or 3 from high nutrient tank?
ORA Tort 11/2004 with nice PE

Same Tort 04/2005 few PE

Thanks,
