Hello Everyone! I see that most in the hobby use an air pump, but I rarely hear of someone using a circulation pump. I was wondering how many of you use them, and what are some of their benefits or reasons as to why you use them. I personally like seeing fish swimming against the current in big tanks and have contemplated getting one for my tank, although that seems to be an unpopular opinion. Tell me what you all think, as well as some experiences you might have had with circulation pumps.
