how much hp is it good for?
The GT pumps are not made to be run full time in a return style system, they are built for variable voltage systems ie returnless. You essentially would have to go with our complete or budget systems as we don't have any hats for the GT pumps anyways. The return style pumps will also support more power, so I think the switch is worth it. Hope that helps, let us know if you have any other questions.
Thanks.
