Order some good cartridges for your filter. What size is your pool?

Our 15ft x 48in Intex went from Louisiana Swamp Stuff to hazy blue in 2 days using Walmart bleach. We upgraded to a sand filter this year and the water was clear in 3 days.
If are going to stay with an Intex brand pool for 2 or 3 years, you might want to look at an Intex sand filter.
