Need Help Please

Ok guys I'm plumbing my new 125 gallon dual overflow tank this weekend and I need to know what size return pumps to get. The tank has 2 1" durso drains and 2 1" return lines (125DT & 40b Sump) I want to run 2 return pumps seperately so if something happened to one I have another. I was thinking of going with 2 mag drive 9.5 pumps ( rated around 950gph or so) would these 2 pumps work well with the 1" drain line. Or are the pumps to powerful for the drains.

I would go with 2 Eheim 1260s personally. You can always put a valve at the outlet to control flow if you find what you get is too big.

It really depends on the head (height) that they need to go...I run a Mag 1800 on a one inch but it is in the basement...the drain is running about 900 GPH.
