What is the difference between a unit for IG vs AG

[PoolDoc]

FYI: "flooded suction" = the pump is below the level of the pool's surface, and the piping is arranged so water will flow naturally by gravity into the pump.

Sorry I was talking about SWG and as to weather we can use a SWG intended for an AG pool in our IG pool. We have been using SWG but it needs to be replaced and because AG units are less I was just wondering if I can purchase an AG as a replacement. We currently have a Circupool RJ series. Had nothing but problems with it.

The only issue with an AG SWG (without a pump) is that the size can be small which might force you to run the pump longer than you want so it could end up costing you more in end. The larger the SWG, the better because it means you can shorten the pump run time and save on energy costs.
