i had to change my sand in the filter this year. ever since then i've been having all sorts of problems. the biggest one is sand in the pool. i thought since we have a lot of sand in the yard that it just needed a good vacuuming but i did that yesterday and today there is more sand in there. so its got to be coming from the filter. plus i've been having to backwash a lot since then. my filter pressure is usually around 20, its been getting over 30 almost every other day. i can look outside and tell by the movement of the water that it needs to backwash again. i've never had these problems before but this is the first time i changed my sand. so what did i screw up?
p.s. i also added some DE to it a few weeks ago to clear up some cloudy water but i was told that would only last until i backwash and i've done that a number of times since then. if that backwashes out, then it cant be the reason the pressure is going up.
