MAG 7 - Free I got one!
Pro's : Reliable and it was free. Small footprint and dosen't toss much heat into the water.
Con's :Will underperform b/c of not enough Head Pressure. At 1 Foot it delivers 650ish GPH and at 3 feet it delivers 500 gph.
Mag 9.5 - 99 LFS
Pro's : Will Satisfy entire needs of she skimmer. Will not over power it like Sen 900 which would require turning down. Works well with Beckett Skimmer. Purchased from LFS so no wait time. No Shipping time. No Wasted Gas picking up package from post office because I get home after they deliver it. I can return it easily if it breaks... Dependable and well known. Easy maintenence.
Con's : Needed to purchase 3/4" barb adaptor. It is larger than the other 3 pumps. It will probably throw off more heat into the water. A Little Bulky in the sump but not too bad.
I decided to go with the MAG 9.5 and 40lbs of Argonite + 40 lbs of Live Sand. 216 Dollars Later + a 50 dollar 5 Gallon Bucked of Salt and I was done. Now I'm poor but can setup my tank!............
I got bad news though. I might not be able to have a refugium because of space constraints.

I'll try though.
