Thanks. I have 100 nassarius snails, 5 Turbos, cleaner shrimp, Green serpent star, 5 emerald crabs, and a couple hermits crawling around. The red and green algae is rock hard-I've tried scraping it off and it won't budge. I have a tiny bit of hair algae but between my turbo's and my molly-its receding. Im looking into a sand sifter since my nassarius just aren't keeping up. My daylights are on for 7 hours a day while my antics are on for 9. I feed one frozen cube every other day. Im topping off with tap water right now (I know-a big "no-no") but Im in the middle of remodeling my kitchen and my R/O system is down for a bit.
