Help me pick Return pumps and Hydor Koralia

Hello all.

I would like your opinions on choosing my return pump and power heads.
I already built my tank stand and picked up 75RR aga tank from the petstore. There is no going back now

Eheim 1260 "635 gph 12'1"Max head 65W" VS Eheim 1262 "900 gph 11'6" Max Head 80W"
Which one would you pick? and why?

If I pick Eheim 1260, the rate that it returns water back to my tank (tank stand + tank height = 4 feet) is about 400GPH.
This is lower than the 600gph that my 75rr overflow will drain down to my tank. This would cause a problem for me right?

If I pick Eheim 1260, the rate that it returns water back to my tank (tank stand + tank height = 4 feet) is about 800GPH.
This is higher than the 600gph that my 75rr overflow will drain down to my tank. This would cause a problem for me right?

I also would like to have two power heads in my tank (mostly LPS and softies). Maybe some SPS in the future

Which one of these two choice would you pick? and why?
1) Two "Hydor Koralia 3"
2) Two ""Hydor Koralia 4"

Thanks

2 hydor koralia 4s would be best IMO

I have a reef ready oceanic that as far as i know uses the same overflow kit. I have a mag 9.5 that works great. As far as the powerheads I opted for maxi jet 1200 with algae free mod kit. I figured if the maxi jet ever dies I'll still have the mod propeller and a new maxi jet is under 20 bucks.

If your overflow is rated to 600gph, you wont have any problems with a 400gph return pump. You will have problems with a 800gph return because the overflow wont be able to keep up.

I have a 75G 48w" which I have a maxijet 400 with the 1600 gph mod(+$20), and it's definitely worth it. for my return pump, I have a blue line aqua 20, which with head loss rates to about 320 gph.

food for thought!

Where do I order the mods. I went to Sure Grip but I don't see anywhere that I can order the Magnetic holder. I am tired of the suction cup on my Maxjet.

thanks

2xKoralia 4's is way too much for a 75g for LPS and softies. I used a Koralia 2 and 3, plus the output from my return when I had a 75g and that was plenty.
