Tony, I don't for a second believe that heat had anything to do with the clam issues last summer. My setup was different then and my temp was stable. I lost all my clams after adding a new one. My current setup fluctuates 4 degrees (F) daily since last fall. My clams are fine.
I think the problem yesterday was that although I have a really good fan, I never turn it on. My evaporation hits about 5g a ay if the fan is on. I guess now I need to make more water instead of leaving the fan off. We'll see tonight when I get home if I'm right about that
