What Current Do RBTAs Like?

[happyclam]

How much current do RBTAs like? Right now I have (4) Koralia 1s (400gph ea.) in my 135 gallon aquarium, is that enough?

my rbta moved semi close to my koralia #2 but its not directly pointed at it....

should be good though on flow

Before I sold off my last BTA it was in my 75 with one Koralia 4, one MJ superflow, and 2 SEIO's 1100;s, and my return which is about 500 gph.

BTA's like random water flow like can be produced with multiple powerheads and/or wavemakes (even cheap ones like the one by hydor), though Seaswirl and others are more expensive and better.

How important is the random flow for RBTA? I am getting ready to set up a tank to house a RBTA. Tank is a 40 Long. I am planning on a flow of about 900 gph which will be divided into 4 different return spots. I was thinking two along the surface/top of tank and the other two about 1/2 way down.

Any suggestions would be great.

Lighting I was planning 4x54w T5 HO on an Icecap 660.
