Ok so my 10 gallon tank is producing so much green water I can't keep up with it , within two days of doing major water changes you can't even see into the tank , I tried a hob filter that diddnt work I tried turning the light off , it got worse , I haven't dosed ferts in a month , will a uv filter help ? And will it be safe for my fish ? Other ideas are welcome , on a good note we had some platy fry show up in the tank out of no where
