How much is to much

[guava62]

I was wondering how much flow is to much. I have about 300 GPH flowing through my 10 gallon. Is this ok, or do i need more?

It depends on what you are trying to keep.

well thats 30x, i think at least 15x is reccommended, but i know ive always gone WAY over that. i find its easier not to work by the rules, but to find whats best for you and stick with that.
but yeah some things cant take that much flow and others can. so you need to take that into consideration before finding out.
