I'm so glad I found this site. We got a Intex easy up pool this summer to see if we liked it and to see if we wanted to go bigger. It's an 18x48 round. It was going great for the first 2 months then a big rain system came through and the pool has been gross. I've put shock, shock, and more shock. I just put bleach in it and it seemed to get milky and we started to vacuum. But the algae is being sucked from the bottom through the filter and out the return. Please help.
