Uv Sterilizers

[penguinpimp1990]

I know theres been a million questions about UV but heres another. Does it eliminate the all the algae or just the "free floating" or whatever. I want to use it in my brackish tank (grows algae like wildfire, like most brackish tanks)

It will clear green water thats about it, it wont cure any other algaes im afraid.
