Hey o-fishy-onados. I have a 90 gal. saltwater tank. One, yellow, sailfin and blue hippo tangs, 2 clowns, 3 cleaner shrimp, a few hermit crabs and a blue tip bubble anemone. Trying to get my nitrates down. Within the last week I just dropped quite a bit of macroalgae in my 20 gal. refugium. Current levels ammonia-0, nitrite-0, pH-8.3, calcium-440, Kh-9, nitrate-40, phosphate-0. I know 0 is a good nitrate level, but what's acceptable? Is duckweed good for saltwater?
