I have a 125 gal. saltwater tank, FOWLR. Recently, hairy algae and an orange residue has accumulated in the tank. I have a complete sump with in-sump protein skimmer w/GENX Submersible pump, pH monitor w/probe, two heaters, an inline chiller, Magnum 350 filter, Koralia powerheads (3). Can you give me some input as to what may be causing these growths?
