Hey guys! Newbie here! I have just purchased a house with an inground pool. The pool has set idle for two years, so it's nasty. We took a water sample to the pool store to see where I should start. Well, anyway we have added chemicals and scooped up leaves for over a week now. The pool store recommended that we change the sand in the pool. Ever since I changed the sand, I've had to backwash the pump very frequently and it seems like the water isn't recirculating like it was before I changed the sand out. I'm wondering if this is normal or if I've put too much sand in the filter. Any help would be appreciate it.
