sigh, i am so frustrated! I closed the valve by what appears to be about half and the de powder is still shooting thru the sand filter. My pool is so dirty looking on the bottom, i have to vacuum to waste to get it out, going thru the filter appears to do nothing! When this pump has to be replaced, what size should I go with? I have a 200lb sand filter a 24'x 52" abouve ground pool (approx 13,000 galllons). My current filter is a jacuzzi 1.5hp.

Im gonna try putting panty hose over my skimmer basket and see if that catches some stuff........
