I was wondering something. I have a 45g right now that’s having some algae issues and wanted to put a UC sterilizer in it but I’m gonna hopefully be setting up a 18g in the next couple months. If I get a UV that’s big enough for the 180 and set it up on the 46 for now will that hurt anything? I know it’s overkill but I don’t want to spend the money on a small one and not be able to use it on the 180
