Hi there,

How much flow do i need for a 450 Gallon. I have a few LPS and want to do SPS.

Note I have 2 Hydor Koralia 8's now with 8 returns
 
You'll probably need some type of external pump.
I use a Reeflo Barracuda with (3) 3/4" returns with flow accerators, and seem to do great. The flow even kicks up the crushed coral at the bottom when all valves are cranked open.
I would still use the Hydors in the corners facing any dead spots from accumulating any waste or uneaten food. Hope that helps.

i use to run 8 koralia 4 on my tank but i just got 2 tunze 6205 and is more than enough . i am also planning to upgrade to 400+ dt that is why i changed my powerhead.
