I have a BGA problem and decided to use Maracyn.

Do I need to turn off the UV sterilizer?
The instructions does not say anything about UV but I know that it affects some medicines. Is Maracyn in that category?

don't turn the UV back on until a full regimen is complete and you already have done the necessary water change and put Carbon in your filter...then turn it back on~

bga is not an algae...it is a photosynthetic bacteria. Though UV is great for bacteria control, the nature of BGA allows it to flouish even with UV until you get to the problem <low circulation, CO2 and NO3> For other algae types especially green water, you cannot beat UV
