Can you use pond treatments for tropical tanks? Are there any to steer clear of, or any that can definitely be used? I've noticed that the local £2 shop is selling big bottles of pond treatments, and wondered if they were a bargain or something to avoid. I'll be checking them out later to see exactly what they are, but thought I'd give you lot a heads up ust in case this is a good do.
