i don't have internet so i am on my phone so bare with me... i bought a bundle of equipment/aquarium one of the pieces was a pentair lifegard model af-93 and af-94 they are already connected. the 94 has some gauges on the top to tell me when to clean the filter. i kinda got excited and blindly bought a via aqua 2600 760 gph pump on ebay. was that a good choice? is it compatible? 55 gal, future reef. if that was the right one do i just run the pump behind the filter to the tank or what? do i need any thing else? sump? any tips? thanks so much
