I have a 15ft. AG Intex metal frame pool. I've purchased the Krystal Clear 14in sand filter and the salt water system. I've got the water pretty clear in just a couple of days, but am left with tons of aglea on the bottom. I have an Aqua Chem vacuum head and hose that I was able to use with the old pump and filter, but can't figure out how to use it with the new sand pump. There has got to be an obvious solution that I'm missing. Any help is appreciated!
