Circulation pump size
Ok folks I have been scouring the internet for an answer and haven't found anything conclusive yet. I need to select a few final pieces of equipment and one is the powerhead for circulation on the 120g reef tank.
The planned flow from the sump will be 1000-1200gph. I was thinking of adding 2 koralia 1150's for in tank circulation. What are your thoughts on circulation planning? I know that there are probably several variables involved so I am somewhat looking for ideas that will leave it scaleable or a good starting point. i.e I don't want to run out and buy something too large but yet I don't want to end up with 6 pumps in the tank etc.
My return lines that are planned will be 3 the left and right will have one nozzle and the middle will have 2 nozzles. As much as I love vortex pumps they are just not in the budget this go around.

I think you are on the right track, but I would suggest 3 powerheads of between 1000 and 14000 gph. In my 120 FOWLR set-up, I have just over 1000 gph in the tank from the return line and three 1200 gph powerheads. I would consider that the minimum for low demanding corals and good biological filtration.
As/if you set-up changes over time and you need more flow, you can always add another power head or wave maker at that point in time.
