I have a question I had a Uv light on my tank until it broke. I don’t have one now and its been almost a year. Some people say you should have one and others say don’t because it also kills the good bacteria. I have a 40 watt one that someone just gave me.
Is it too big if I find out I need one? I have a 75-gallon.
