I'm considering a UV sterilizer. I really want to keep plants with my Tangs, but I can't seem to find the right balance of lighting, ferts, or CO2 to keep the algae at bay. I've got 154 watts on the 75, and I've got a hell of a diatom bloom right now. I figured it would happen, but I'm a bit miffed that all my pretty white rocks are getting browner by the hour. I know the diatom bloom will go away in a few weeks, but I'm wondering if maybe I should cut back on the lights even more.Thanks all for your support i agree with you afro i believe the smell was intense due to the algae covering all the anubias plants and such and with all the dead spots where i had all of that rock in there pretty strong and i was just getting tired of smelling that crap when i walk into the living room. hehehe
