I'm confused why people want uv
sterilzers in aquariums. They kill bacteria. We want bacteria.
Sure they kill algae as well, but the problem algae is the stuff already attached to rocks, walls etc. same for other bad blooms. The uv
sterilizers don't do anything for the root problems and to me seem to be a waste of money in aquariums. Or am I missing something?
I do have one in my hottub tho. Need to kill ALL bacteria in there. Helps with the bromine needed
