I have 20g Long tank with 3 fish and just 2 xenia frags. I just put in my 850 Gph power head, it seems really powerful but not too powerful. I made it faced to the surface Would this be too much? this is the only power head i have in the tank.
850gph too much for 20g?

If you sand is staying down and its not to violent on your coral then your good. Most powerheads dont actually put out what they say so I would assume you have about 30 times turnover give or take a little and thats a good number
