I just have a few questions regarding the title. What sort of size UV am I looking at for a 300 L tank and a 700 L tank, having a problem with ich so want to introduce the UV just in case.
secondly if I do a copper treatment; how do I maintain the therapeutic levels? I can’t be testing the water every hour?
