After the clam spawn everything has settled down nicely. I did two water changes that night 120 gal at 1:00 AM an another about 60 gal at 4. Actually after the Squamosas began to spawn so did all the Gigas, some of the larger maximas and some of the smaller Croceas. The tank actually looked like Kalk water stirred-up. Put fresh carbon in large bags and replaced 12X12 poloy pads in system. Actually the skimmer did nothing. The water was so flat that just today it is really starting to skim.I think the water volumn and water changes saved me. Some of these clams I've had for seven years and never anything like this. I have had a 15" Gigas spawn and once in a while a maxima. But it does not trigger the massive event of the other night. Two things I did that day somewhat different. I took one of the large squamosas out of the tank to clean some sponge off his shell. I've done this before with no adverse effects. Then while watching a ballgame I took my large turkey baster and blasted areas where food, debris sometime get trapped in the rok crevices. I've done this many times before and nothing happens. Good way to feed a tank from time to time The water was cloudy but nothing unusual. Maybe it was the combo of both events the same day that stressed out the one Squamosa and others also. I'll try to get some pics over the weekend and download thanks for concern
