How long for UV to clear up green water?
My 135g has cloudy green water. I just put a 18w uv sterilizer in. I tried to aim the output as closely as possible to the entrance of the skimmer.
How long did it take to clear up your cloudy water? |

Kinda hard to say exactly how long, to many variables
How yellow the water is..... How much flow through the skimmer..... I would think within a few days you should be clear.... That's if the flow is slow enough

If it is a new bulb usually overnight.

If it's properly sized, hours.

Oops.... Didn't mean flow through skimmer, mean flow through uv
Big uv will clear up in hrs.... I would think 18w and 125g would be a day or two but hard to say

maybe undersized?
I think 18 watts is efficient for 100 or less and 25 would be more suited I know slow flow is recommended for parasites but bacteria and algae would need more flow so a higher watt unit may be more prudent. Just my .02 tivo edit: there's charts out there for size and flow rates
