70 gallon flow

[DaveP]

I need to increase the flow in a 70 gallon tank.

I am planning on the following setup, please let me know your thoughts!

2 - Hydor Koralia 2 Powerhead 600 gph
1 - JBJ Ocean Pulse - DUO Wavemaker

Thanks!

I would go for at least Koralia 3 or 4. I have 2 Koralia 4's on my 75 and I still want more flow. But a #2 is definitely too little IMO.

I agree. I have a 3 and a 4 in my 75 and I'm probably going to add another 4.

wow, i have 1 #4 in my 80gallon bow and the flow is pretty intense do you guys have alot of rockwork to disrupt the flow?

[DaveP]

Great, thanks for the info!

I'll go with 2 - 3's

I agree with what has been said. The more flow the better, I have 2 Tunze 6045's (1200gph), two smaller powerheads (300/gph ea.) and my return from my sump, in my 75 gallon. Granted it will depend on what you want to keep, but with both the Koralias and the Tunze's, the flow is more dispersed, so it is easier on all of the corals and fish

A 70 tall? In that case w/3' tank, 2 - #3's would be good for lps & sps to start.
