Hello all, I am looking for a uv sterilizer for my 55 gallon tank with a 10 gallon sump. I am currently having some algae issues caused by my light and I have green water which is why I am considering this. HOB or in-tank would be best but I will consider others as well. Any recommendations help. (And before you ask about the issue, it is the intensity of my whites. I need a par meter to reconfigure the spectrum but I will probably not get an accurate reading with the algae in the water column.) thanks.
