I have had a green and a pink birdsnest now for 3 months. I have had good growth and great extension. I noticed yesterday that the green one has one side where the polyps are not extended and a few patches of necrosis. The necrosis may have been when the snail knocked it off down through the frogspawn to the sand. But this one whole side doesn't look good. I moved it lower in the tank today to see if that helps.
My pink birdsnest has a spot at the base completely missing. This could be from a hermit crab eating the algae, shadowing or something else.
I add a protein skimmer about 10 days ago and had been using just a refugium before then. The only other thing is that my alk moved from 9.3 to 8.8 and then back about 2 weeks ago. But I have had this degree of variation before in my smaller tank and it was fine in there.
It has been steady since. Is this related to the protein skimmer? Monti's, stylo, LPS and softies all look great and are growing.
