I've had this 6" "Dermosa" clam for about 4 months with no issues.
A couple months b4 that I implemented incremental AWC, and the tank had never looked better.
In preparation for moving to a new tank, I decided to make sure my parameters were in sync with the tanks and decided to check Phosphate and NItrates (which I never really every check...the tank is 7 plus years old). To my surprise, my phosphates were .87ppm.
Since the tank looked great and had no algae issues, I figured I should investigate slowly lowering my Phosphates in current tank and not shock my corals during the move.
I tried early replacement of my Chemipure Blue and adding macro algae back to the tank. Neither of which impacted phosphates as the macro algae never took hold.
Keeping things slow, I added a phosphate pad to start slowly bringing the number down.
In about 36hrs I went from .87 to .71...but noticed my clam went from fully open to mostly closed.
I removed the phosphate pad 24hrs ago, but the clam has not gone back to being happy.
I'm not sure the phosphate pad is the source of the problem, but there are really no significant changes to the tank.
Parameters look good:
Salinity: 1.024
Ph: 8.05
Temp: 77.7
Alk: 8.2
Calcium: 442
Phosphate: .77
Nitrates: 15
All my other fish and corals are doing fine.
I know people are going to point to Phosphate and Nitrates, but these numbers have probably been steady for a couple years.
Any thoughts?
