What is that directly under the hippo and yellow tang? Are you running your sump on a reverse light cycle? What is in the sump? I.e. macro, LR, DSB?

did you check for CO2 buildup? take a cup of tank water and test the pH. then take that cup of water outside of your house and aerate it with and air stone for about 30 minutes. if the pH rises, it means you have a buildup of CO2. this could be tank specific or in your house in general if you are not letting enough fresh air in.

that's my derasa clam - sump lights on 24hrs - LR and macro, but the macro doesnt thrive...I think it also wants a higher Ph range - no issues with CO2/enviornment air, but there are always bubbles..small ones coming from my LR? - Ph range maintains at 8.
