Hey guys, I need a little help. I have 2 clams in my tank and yesterday I noticed they aren't doing well. Their shells are wide open, not closing even when i touch them. I believe that's what is called gaping. Everything else in my tank is doing great including all SPS. I'll give you my water parameters at the end of my post. I did have a problem with some SPS bleaching last week so I turned down my newly placed LED's. The only thing that changed was I swapped over from Reef Crystals to Salinity by Aqua-Vitro. Any help would be greatly appreciated.
