My clam is getting brown stripes in it's mantel. I've had it for about 4-5 months now. I know that they change colors but just wanted to run it by someone with more experience with clams. Lighting is t5 75/25 and an aqua blue plus from reefgeek. 39 watts each. I did have it under an aquasun lamp up untill 1 1/2 weeks ago but my other corals were bleaching so I swiched to the 75/25. It was starting to do this before the swich though. water perams are good except for the sg which today was 1.030. I'm working on getting that back down to 1.025-4. the only other problem I'm having is keeping the pH up even though alk and cal are 8 and 420 respectivly. PH runs about 7.7. temp 80.8F. Any thoughts. Thanks. Oh yeah the clam is about 9 inches from the light.
