I have a 46 gallon bowfront aquarium and I don't know what wattage of uv
sterilizer to buy. I've been fighting an algae bloom for 5 months now it was so bad about 4 months ago you couldn't even see inside the tank. I completely blocked off the light in the tank with solar curtains and left the tank light off for weeks which I hate to do because I know it stresses out fish but all that's in there right now is a common pleco and I don't think it bothers it to much. I have a freshwater aquarium and no sump tank to speak of so what kind of sterilizer can I buy that's inside the aquarium and what's the specific name for those types. If someone could send me a link to a good sterilizer that's not that big that would be very helpful.
P.S. also I know virtually nothing about UV
sterilizers so at the very least some info would be very much appreciated thank you
