Looking to add one of these sand filters to our pool. Intex 16'x48" Ultra Frame (5000 gallons).

Here is the Hayward: http://www.poolproducts.com/SPP/prod...=AMAZON&FNM=92
Here is the Intex: http://www.amazon.com/2650-Gallon-Sa...9396188&sr=8-3

Which filter would you guys recommend or a different one all together?
I am wanting to be able to run a vacuum as well, any recommendations on a decent one that would work with either of these filter systems?

Thanks in advance,
Greg
