Mag pumps have worked great for me. Maybe a mag 12?
With a HOB overflow you will want to make sure that the overflow can handle the pump you run. Otherwise you will flood your display tank.

I would buy an oversized pump but throttle it back with a valve. You can always use a big pump and when it gets dirty or older, it can still move water the way you want.
For plumbing, you need to visit a few tanks to see how it can be done. It's fruitless to try and describe it here, even with pics.

ok, thanks for the help... ryan at aquatic just ordered in my mag 9, hopefully it will be big enough for what i want, i only need 750 GPH to cycle my tank 10 times, so i have about 200 gallons that it can lose when it becomes more inneficcient.. ryan convinced me to run his backpack overflow and we are going to be running a sump with a refugium in it.. the 29 gallon is going in today to get acrylic cut and installed in it. ill post some pics on friday when its all set up and ready to go

That Mag9.5 will probably only give you 500 - 600 gph, just so you know.

Mag pumps are rated at no head pressure. Since you will likely be pumping up about 4-5 feet you will lose some pressure and thus gallons per hour. My Mag 18 gives me probably 900-1100 GPH at 4 feet of head. The higher it has to pump the more GPH it will lose and the faster it looses it. Also each angle in the plumbing will slow that flow even more.

What Will said.
If you figure you'll be lifting about 5 ft and have 3 elbows, you'll see about 500 - 600 gph with that pump. It will drop off (pretty dramatically) from there as your lines foul and you get stuff growing in them.

i should only have about 2 -3 feet of vertical pipe from the pump to the tank, and it should be a straight shot with two 90's.. (i hope)

Okay so for a new guy, what is the calculation or determination for tank capacity versus turnover? Did that make sense? If I have a 100g tank, what is the rule of thumb for how often the water needs to be turned over?

the tank needs to be turned over ten times in an hour... at least thats what most people recommend.. therefore you would need a 1000 GPH pump to feed it and turn it over with best results

actually according to whats said in here you would need a little more than 1000 to make up for bends/pressure/pump wear..

if you go to reefcentral there is a calc that figures everything you just enter how many 90's and the height and select the pump you want and it will tell you what you get

Total losses are 4.89 feet of head pressure, or 2.11 PSI. with a flow rate of 772 GPH. Process took 94 iterations.
awesome calculator.. i think i will be just fine with a mag 9 it looks like :) until it starts to break in and decrease flow a bit.

I always get a pump that is rated bigger than what I need. Like Mark said, you can control the flow with a valve, and then as the pump gets older and stuff grows in your lines you'll still get the same amount of flow. My recommendation, go with a bigger pump than the mag 9. You'll wish you had later on. 
As for the turning your water over 10 times an hour. Thats a good start, but I like it more. I think my tank is doing about 15 times an hour. But thats my own personnal opinion.
What is everyone else doing as far as water flow??

I like the mag pumps, very cheap, very quiet if installed correctly. Id say get at least a mag 12 for a 75 gallon.

oh, make sure your overflow can handle that much water flow.

My father-in-law's 72 gallon bowfront has a Mag18 for a return and I think it's just right. He has three outlets and has very good currents. He also has a PH in the tank. Oh, we had to modify his overflow to handle the flow from the Mag18.
Lost, if you have additional PHs in the tank, you'll be fine with the Mag9.5 (but I agree with the others who suggest going bigger). Just don't rely soley on the return pump for all your tanks circulation.

I'm planning a velocity t4 for closed loop, which will push about 1200
gph, and then a return pump from the sump pushing about 400 gph, which
totals 1600 gph which is 20+ times turnover in my 75 gal.

Was that in there yesterday? Casper--WY windier than ?
Down to a 20, soon to double or nothing

im actually running a maxi jet 1200 and a maxi jet 900 in the tank as well as the return pump... not sure how many GPH they flow??? but they will be in the tank as well adding current and flow
