general sump pump suitable?

[knickle22]

Due to stand restrictions i cannot fit a large sump under my main tank and because of this i am setting up a sump tank in my basement. how ever finding a pump to push appx 1200 gph to a height of 12' is pretty pricey. Just wondering if ordinary sump pumps such as the ones at home depot well work. or well they corrode from salt or release harmful chems to my tank?
I was looking at this pump as the flow chart shows pretty much the flow i need but is a fraction of the price vs the reeflo pumps. http://www.homedepot.ca/product/util...sepower/928227
