Ok most of you know I have been slamming. I generally only backwash when flow from return slows or if when pressure rises with DE in filter. I noticed despite vacuuming that I would have a teaspoon/tablespoon of sand in pool after backwashing and rinsing. I vacuumed it up again and then decided to put a skimmer sock over the return to see if it was spitting sand. Low and behold it is. I will post the pic of it in a minute. Please not the pic was taken in shade and I had the phone real close so clarity of water looks funny.
Here is the pic, see the sand in the toe?
