No matter what I do I cannot get my acros to grow. Some acros are good, and some are not. Monti cap are not doing well either. Parameters are as fokkow. Dkh 8-9 and not a huge swing at all might go up one day then down the next but nothing more than .5, calcium 440, mag 1460, po4 between .04-.11. I don’t run gfo that often and now I won’t do it cause it’s stripping my nutrients in the tank. I run my refugium light 24/7. My zoa and other lps are thriving and growing like crazy with a lot of poly extension. It is a 90g tank with a calcium reactor. I run a chiller on the tank so temp isn’t an issue with 3 different heaters on my apex(you ever know). Mp40 one side, maxspec gyre 250 on the other. Both run thru my apex. Any help with this to make this good. I’m also thinking of doing bare bottom as I have sand in the tank now.
