hey everyone, still considering my birthday present and i was reading the thread on greenwater and then a uv sterilizer popped into my mind anyways, is it benifical to have it in a freshwater tank? does it get rid of algae? if so what kinds? i know it gets rid of green water but i dont know if it gets rid of any other ones. Also what kind of parasites does it get rid of that can affect my fish? (what kind of diseases does it protect from?) try to keep the scientific names to a low amount cause my little brain can't take it and i wont know what the heck your talking about
