Thanks Jason, now my button colony is engulfed with white mold. Take them out and just keep the ones not molded? Have had 20 crabs all over the orange colony. They cleaned it up but the small heads don't seem to be opening. Skimmer died, looking to replace asap. Is it safe to order over e-bay. Got the salinity gizmo and water tested exactly the same as my $5.00 plastic job. Missed you at Easter but your wife looks great.
