# of Powerheads and flow

[mosssw]

Hello all,

I currently have one Tunze 6045 and the return in my 90G for flow and know I need more flow. I am thinking about adding 1 Korilla for now, do I need a 3 or 4? and will that be enough or do I need a third? And how should they be placed?

Thank you
Shelley

What type of corals, if any, are you planning to add? This will factor in on the amount of flow you'll need.
