I get sand in my pool, so I ran the Aquabot, washed out the filter bag, and retrieved the sand it cleaned from the pool. (There are some larger grains of sand in the pictures, so I am going to check for broken laterals. Also, we have lots of birds in the neighborhood, and maybe some sand gets deposited by their poop????)
Then I sprinkled it over a new lateral, to see what would get inside the lateral.
Then dumped out the sand inside the lateral onto a sheet of paper.
I replaced the sand years ago with sand from a local pool store. So, either the sand grains are wearing down and many are now small enough to enter the laterals, or the sand I bought had poor quality control. Anyone bought crappy pool sand and had this happen? I really doubt it is wearing down and getting smaller. As I said earlier, I'm going to empty the filter to check the laterals, so have to replace this bad sand.
So can anyone recommend a quality brand of sand I should look for?
