I'm with Poconos on this--get the SuperPump, but get the 2 speed. You'll LOVE a 2 speed.

I have the 1hp 2 speed Superpump with a 200# T210 filter and it's FINE. The 300# will work even better--no chance of over-pumping your filter.

The two speed is INCREDIBLY quiet in low--as Poconos-- he's seen /heard mine. So has Watermom, my fellow moderators.
