Hello,

I have some green water and i am told to get a uv steralizer.
Not sure what to get.

Looking at
Deep blue
Green killing machine

Does anyone have anynsuggestions?

90 gallon fish only salt tank. Set up and running.
Salinity 1.018, ph 8.2' 0 nitrite

Water was a little green, fed less and killed lights and it cleared up, today i got a new fish and I put fish in with water from fish store, water went green within 2 hours.

When runnung uv steralizer, how long do you run each day? Do younrun every day?
