Help Curing Brown Algae / Diatom Bloom?

You're running the lights way too long. If they are at 100%, they are equivalent to 2 250watt metal halides on a 65 gal. Try cutting back the lights to 60% and cut back the time to about 7 hours. Since you don't have many corals at the moment, try leaving the lights off for 3 or 4 days until the brown algae subsides, then gradually bring them bak on

Okay Ill do both of those things today when I'm off work. The only adjustable settings on the kessils is brightness and either tuna blue to white light. When you say put them down to 60% do you mean the brightness? Thanks I'll keep them off for a few days.

yes, try to bring the brightness down to about half. 2 tuna blues are a lot for a 65 gallon. Try keeping the lights off for a few days til the brown algae disappears. If you're in a bright room, maybe even wrap the tank with a blanket so you get total darkness. Remember, Light+nutrients = Algae blooms.
