What is the GPH/Turnover rate in your tank?

[uwdanno]

I have a 4 gal tank with the return pump set to about 56 gph. This turns my tank over >14 times per hour.

 

Its still a new tank and has only been up for about 3-4 weeks. I'm waiting to see how my corals react before I upgrade to higher gph. Right now I have LPS and softies.

 

What is everyone else using for a turnover rate?

I aim for 10-20ish for a reef tank. Some suggest higher, and I would, my corals just don't like that much. I'm currently at 100 gph (lowest setting on the AC70) for my 5 gallon. It's even a bit much.

In my 20 gallon ive got 1300 gph, but have most of the flow in the upper portion of the water column and only a light undertow going on down below. In smaller tanks it wan be really tough to get good turn over without directly blasting everything tho.

It can be hard to find a happy medium between good flow and blasting corals in a 4 gallon tank. I have a jbj pico that the hang on back filter is enough but Its a big 50 gallon rated fitler on a 3 gallon. The GSP in this tank is spreading like crazy. I tried to put a power head in the thing and I could never get that to work. I also have an ecopico that is 12 inchs tall that has a powerhead and that with the filter gives it a perfect balance aimed towards the front of the tank which is 10 by 10 by 12.

 

You have to find the balance that helps your corals grow and fish thrive.
