Suggestions for new return pump

[B-ridge]

i have a 240 gallon display tank on first floor of my house. My sump which is a 125 gallon and my 75 gallon fuge are located in my basement. I have a reeflo hammerhead gold which is connected to 125 sump through a bulkhead and some piping externally. It pushes the water up approxiametely 8-10 feet before coming out of 4 nozzles. I'm not exactly sure how to measure the return of water to our tanks/gph for my tank. I am running 4 mp40's on display tank. It is a room divider so it can be seen from both sides. Mp40's are facing each other 2 on each sides
So with that said I would like some suggestions on a new return pump that would be ok with my set up. I do plan on getting sps corals like birdsnest. Branching montipora. Montipora caps. Digitata and pocillopora. As well as swaying lps like Duncan's. torches. Frogspawn. Hammers. Elegance. Anything that sways. Lobo's. anemones. Zoas. Etc.
thanks in advance

I have a 180 gallon aquarium and a 75 gallon sump in the basement. I use a high head pump which is a Pan World NH-200PS. That's what's on the nameplate. Most of these pumps are rebranded by other companies. It's a great pump that is rated for something like 1740 gosh and 40 ft of head..

I'm using the panworld 150ps on my 125 gallon. The panworld 250 ps would give you enough flow and possibly enough to run reactors off it.

So how does a person calculate the gph they need? I'm trying to see which pumps I can get away with that doesn't use as much energy as the reeflo hammerhead. Seems like I'm just wasting electricity unnecessarily
