Earlier I posted about yellow cloudy water...my colors were off. LOL It's green, so likely an algae bloom. First picture is today, second picture is 2 days ago... If I purchased a small submersible uv light and put it into an old hob filter (the light would be the only thing inside it no filter media etc). Would that work? Or is there a better idea? Will it kill off my beneficial bacteria, hurt my live plants, fish, or inverts, perhaps eggs/fry?
