I really have a question and a concern. We have a 10 x 30 summer escapes. The pump that came with is was junk so I bought a Intex 1600 gph sand filter. After getting it set up and letting it run, I noticed sand in various places on the bottom. I thought maybe the new pump was just moving more water and moving things around, so I vacummed. After about 30 minutes, I noticed sand on the bottom again. I bought the sand from a home improvement store and it said it was pool filter silica sand, 20/40 gradation. So, did I get the worng sand?
Second, my old pump had filters in it that allowed me to put 1" chlorine tablets inside the filter. With the new pump, will I need to change to a different chlorination method? Will I have to switch to granuales or use a floater? Or just add bleach from the BBB?
Any suggestions would be greatly appreciated.
