I currently don’t have a ton of corals, but a decent amount. I broadcast AB+ every other day and use reef roids twice a week as my acans, bowers, symphyllia, and scoly respond really well to that. Even seems like my torches do too. But it cranks up my PO4. Is there something else I could use for the same response or a better way to control PO4? While my tank was fallow the PO4 went up to .061 (Hanna), almost doubled what was before. I just added two fair back in. I do a 10g WC every week on my 65g. I assume the AB+ is helping as my two SPS and zoas are doing really well.
