First let me say sorry For the lazy question but I have run out of time and don't understand it all. I have a hayward s244t sand filter and a matrix power flo 1 HP 2 speed pump. My question is, how long would it take for this combination to turn over a 28k pool on low? It is plumbed with 2" PVC. The run from the skimmer to the pump is 15' and same for the return to the pool. The pool is 48". Thank you for the help.
