Clam fresh water dip

[Myka]

I use lots of GFO in my tanks too, and I have two clams. It has never bothered my clams, but in some cases if you remove GFO from a clam with pinched mantle it will resolve itself. I don't like doing dips on clams either, but pinched mantle is serious and needs to be caught early. Most people who lose clams in a dip don't dip early enough and the clam is beyond the hope of any return.
