I hae 2 Max and 1 Croceca calm. 4 weeks ago I treated my tank with Chemiclean for Cyano. My clams did not like this and closed up. I am sure the Chemiclean made them mad. One the smallest Max has opened back up and is very happ. The other 2 just are not extending out. I have changed water several times and my parameters are all in line. Should I do a freshwater dip and see if that helps or just continue to wait it out?
