Which pump IYO/IYE?

[DMasker]

So I am setting up my 180 and am building a sump for it. I have two DIY overflows I built with 1" PVC so it should equal 1200 GPH on those and I have three emergency drains that are 3/4" in case something happens to my DIY overflows. So my question is which return pump should I get? BTW its about 4.5 feet up to the tank and about 3ish feet horizontally.

I am deciding between the following:

Mag 18 from Foster and Smith ($144)

Or a quiet one rated at 1500 GPH for ($100)

I am leaning towards the Mag 18 because I hear good things about them, and at 3 feet its rated at 1375 GPH instead of 1800 GPH. So if my math is correct that would give me 1161 GPH at 4.5 feet of head?

BTW this is my very first sump experience so any and all advice is welcomed.

I've used them in the past and they have very good pricing on a ton of different pumps and quick with shipping.

I was using a Mag18 and a Mag7 on a tank with two 1" drains and they did not flow as much as I would like at 5-1/2 feet head. Mebbe look at the Mag24, you can always tee off excess if you have any.
