help with powerheads

[gpkozmp]

What size powerheads would be goog in a 100 gallon tank, I was thinking of getting Koralia 4's but was not sure, a little help please...

It depends on what you plan on keeping. For SPS I would get at least a 20-30x turnover rate between your powerheads and return pump.

I have a 90 gal. and i run 2 Koralia 3's they seem to be just right. On top of that flow you have the circulation through the sump, i think mine is approx 400gph and then i have a cansiter filter i use for carbon and other medias like a reactor which i would say is flowing about 200 gph. One thing about the Koralia's, if you remove the front grill from it and the bezel that directs the flow you get really good flow in all directions, instead of a massive jet in just one direction.
