That pump is probably too much for that filter as it probably pumps in the 100 GPM range and the filter is rated for 80 GPM. I would look at one of Haywards Larger DE Filters, maybe in the 60 square foot range. You will appreciate the better technology, as well as much longer time between backwashing. Also, the 60 sq. ft. filter is rated for 120 GPM.
