Green water?

[alzika]

My water has been green for 2 weeks!

I tested all parameters and they are fine. 0 nitrates, ammonia, and nitries. I am using RO/DI water and it has a TDS reading of 0.

I run my lights for 6-8 hours daily and the tank is not next to a window.

Please help, I don't know what is causing this...

Sounds like a phyto bloom. Do you have any fish/corals in the tank right now?

shut lights off for 3 days . It worked for me

I took four steps and it cleared the problem up in 2 days:

1) Ran a UV steralizer
2) Put some clarify chemicals into the tank
3) Temporarily put a hang on filter on the tank
4) Ran my skimmer very very wet
