How much circulation is too much?

Have been thinking about this.... Fish seem happy... But I think it may be a bit much... Forgot the gph of my power heads. Will check tonight, about how much sounds right for a 65?

I think it would be good to have maybe about 20-30x turnover in a tank per hour. Hopefully other people will correct me if I'm wrong.

Yeah that's right. You can have more than that -- some people have 30x to 60x turnover. It also depends on what type of livestock you have. Some corals require much higher flow than others.

I'm putting two Koralia 750's and a Mag 7 in my 55 if that helps..

As long as the substrate is staying on the bottom, you don't have too much flow.
