Who Gives A Fish Forums

Thanks for the tips, gonna test alk and phosphates tonight. Lights are on for 10 hours, might cut it to 9. Forgot to mention I'm using Red Sea Coral Pro salt, mixed last week.

My Zoanthids started turning brown last week. Tank's a 40-gallon with AI Prime lighting, running for about 8 months. Params are 0 ammonia, 0 nitrite, 10 nitrate, 8.2 pH, 1.025 salinity. Got a pair of Clowns and a Cleaner Shrimp in there. Been feeding Reef Roids twice a week. What's the deal?
