What size drain(s) does your tank have? For the gallonage you are going to move with that pump you will need several larger drains.
I agree about not buying a Mag pump, they are not very efficient and they create a lot of heat. I still dont get why they would tell you to buy a bigger pump only to throttle it back? Why not just buy the correct size pump? Regardless of what you do though, you WILL have to put something electrical in water in this hobby eventually.
