I've been fighting gha for 3 months. I got it down 80% and it's brushing off the rocks nicely. Filter now has uv light, algea scrubber, active charcoal and a reef mat I also have over 300 pounds of live rock. I went from the really high nitrate and phosphate down to 0 nitrate and very low phos. Now I need to help my xenia's and zoas. What can I give them without feeding gha. I don't understand the differences between amino organic or red sea and+. Thank you for the help.
