Uv ligjt to control algea?

[MSC1973]

An I use a 55w uv light to control my algea? Will it harm the fish. Parameters are good but phosphate at 1 I'm working on that but can I use the light sparingly to knock off the algrea?

dont waste your time. track down the cause of the excessive phosphates, get them under control and you wont need a uv

Yes trying to track it I have a ro unit comming I'm hoping that will fix the issue

it should help cut back on the algae a good bit. my algae battle has decreased significantly since installing a rodi.

Unless you have phosphates in your source water using a ro/di isn't going to decrease them any. Have you thought about running some phosphate removal media in a HOB filter?

I find grape caulerpa to be great at consuming phosphate in a tank with a refugium.
