Flow for LPS

[scotmc]

What is a good flow for LPs coral? I am around 40x as of now. Iam thinking it's a little too much. I have to move my Brain, due to flow receding the tissue.

You really can't go by the turn over rate. The flow depends on the type of flow your talking about. You can have a 600gph that is in a direct stream that is far more damaging than 2000gph that is a random gentle flow -more spread out. So the velocity is the key or problem depending on how you look at it. From observations in my tank, most lps like to have a gentle swaying motion, back and forth, going on. They do not like to be pushed to one side because the flow is so strong. So to answer you question the 40x turn over rate depends on how the return lines are putting the water back into the tank.

Iam running 2 tunze 6045 and one 6055. I am working on moving them to different positions. I am wonder if I need 3 of them.
