Looks like it could be the beginnings of pinched mantle.

Here is a link to some info that may be of help. A 30 minute freshwater dip may do the trick.

There is some speculation that carbon may play a role in pinched mantle too. Have you ran carbon lately? I run it 24/7 and have never seen a problem with the clams I have so I am not convinced, but its something to consider.

yeah, i've read that too. agh, i just don't want to put my clam under stress if it's not really it, but i might as well as a preventative. what should i use to up the pH of the RO water, alk solution or something?
