Intex pool circulation vs. typical inground ??

This issue seems to be return exit velocity. The flow rate is so low with the 1500 GPH pump that it doesn't seem to move the water very much. Based upon other Intex pool owner experiences, the 2500 GPH pump/filter should do the trick.

Thank you -- this is very educational!

I wonder if exit velocity can be improved by changing the fitting at the return -- maybe narrowing the stream of water and aiming it to go more directly across the pool. Once we have the larger pool set up, we may try experimenting a bit (we're high on DIY capabilities, not so high on $$ here ).

Reducing the size of the return orifice will increase the exit velocity but it will also increase head loss so flow rate is reduced some. But for most pumps, this will still increase the exit velocity. I am not entirely sure about the 1500 GPH pump.
