Getting Rid of my Maxijets~

[Noober]

Ok its time i invest in a good flow system. I really want the tunze controller with some 300 dollar powerheads but i'm not gonna be able to push that kinda cash and get the new skimmer and calc reactor i want.
So i was thinking of going the Hydor Koralia Magnum Circulation powerhead for my 120 gallon tank. I have a magdrive return pump that is rated at 1200 gph and its got two 90 degree turns in the pipe and about 5 ft of climb, I'm thinking now i'm looking at closer to 1000-1100 gph at the most. Soon if i add some more inline filteration it will be even less. So 2400 gph is 20x turnover rate per hour in my display tank. How many gallons per hour should I get on each powerhead, would two powerheads be plenty with a decent wavemaker like the redsea wavemaster pro. Or should i take advantage of all four outputs on it and get 4 of the weakest power heads they make. I am not sure if i should get the magnums, which are their new and improved powerful powerheads, or if the old ones that will hit near 1000 gph would be fine. I eventually want to have a sps dominant tank, and slowly but surely I am getting the equipment that I need and trying to learn the art of it all. Please give me your advise! Thanks!

Wait edit that, I just found out hydor Koralia makes a 4 series powerhead with controllable speed. I guess now I'll find out if it works with other wavemaker systems. Anyone tried these?
