Hey Zoa gang. A quick question re: Zoa's and GSP's I have had my new 30 gallon tank up and running now for about 2 months. Initially I put in a Xenia colony, growing really well, as are the rainbow star polyps. A week ago I added a few Zoas and a daisy polyp frag as well as a gsp - none of them have opened though I have left them alone for a week, I tried them in higher flow/light a few days ago but they still will not open. The GSP has basically made itself into a little ball and the daisy polyps as well. The only other occupants of the tank are my 2 juvenile clownfish, a few Nerite snails a few Nassarius snails and some Trochus snails. . My parameters seem fine with the exception of ALK being low the week when I just tested it. Would this affect the Zoas etc? I spoke to the owner at the LFS and he was surprised as he said that Xenia are less forgiving than Zoas. IDK as they started with 1 stalk and now have 5. Here is an overview of the parameters.
There was a spike in Nitrate/ammonia a while ago as the LFS sold me aster snails instead of Trochus and they all ended up dying as they could not get up after they fell on the sand bed.
I do a 10% RODI water change once a week, There is significant coralline algae growth happening, so I presume that this is likely causing the ALK to drop?? Any help appreciated. I have read that Zoas can take a while to open, but ??? They were all fully open and happy at the LFS, as were the Daisy and GSP.
