I had my 39 gal sw
aquarium for 4 years, and tried everything to get it under control... Snails and hermit crabs, tear down and clean, changing lighting (3 times), changing filtration systems (also 3 times), phosphate sponges, coral, live rock, live sand, RO
water, deionized water, and even tried that Bi Aquaculture stuff that "guarantees" no more algae. Nothing worked... I finally did come up with a solution... I gave my fish over to someone who had a marine tank that was maintained by a lfs
cleaning service, and switched my tank to freshwater. Worked like a charm. Now I've got a sparkling clear tank with plants, and no algae.
I know... Not what you want to hear, but it's the only thing that worked (for me)... I literally put thousands of $$$ into trying to fix it, and that's all that worked. The sw
fish and critters were cool, but I could never keep up with the maintenance. I would rather have fw
fish that I can actually see. LOL
