Flow For Coral

[SinkyShippy]

I have a 20 gallon high tank. I will be looking to add coral. How much flow should I have if I want to add coral that require moderate flow? I currently have two hydro koralia nano 240gph circulation pumps in my tank

Is it a 20 long? I have a either a 240 and 425gph or 2 425gph koralias in my 20L. One of them is on a 5 sec timer. It’s working for my zoas and gsp. It “could” be enough but some more would not hurt. Just gotta pick a good spot to put your coral in relation to the flow.

I have had those two in my 29 gal and should be fine I did add two tunzes recently because I have a lot of rock and some sps that needed more flow; They are hooked up to an apex and all 4 only run a few times a day
