Can someone advise me on how to install a phoseban reactor in my sump. 75 gal mixed aquarium? The sump( apx. 15 gal) is a three compartment sump.( leftside,water inlet with a sock and skimmer;middle, the return with auto top off switch; right side, refugium.)Where is the best place to put a reactor? and do they really work to reduce phosphates? By the way, I have an outbreak of hair algea in my well established tank. This is the reason I think I need the reactor. Any suggestions would be appreciated. Thanks, Ron.
