Was talking with a guy who works at my LFS and was telling him my zoas never grow well he mentioned they like dirtier water sometimes and asked what my phosphates are I said generally around .05-.08 he said that’s too clean in his opinion he said his personal tank is .3 not .03 but .3 and said his zoas thrive in that . Isn’t .3 ridiculously high? He also said he has no algae problems.
