Hey all, my current PO4 is 0.22. I am looking to lower that. I have a Red Sea Reefer 250 G2+ System (54 Gal Display, 11 Gal Sump). I am running RowaPhos in the Reefmat 250 media basket but it has not done much. Before I try any liquid additive I was thinking of maybe trying a GFO reactor. I do not have a lot of room in sump so thinking maybe BRS Mini Reactor - 5" Single with Sicce Syncra 1.5 Pump. Thoughts?
