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.If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.
