When I got my sand filter (details in sig) I added the correct amount of sand (I think at least) this year as I was redoing my pump area I noticed the sand looked low, it appears to be apx 1/4 to 1/3 full of sand. Does anybody know how far from the top the sand should be? I'd expect to have maby 10 inches on gap, closer to 2/3 full of sand.
Also I've noticed I am getting some small particles from the return, very small what look to be parts of flowers (maby seeds, less then 1/16th of a inch in size), is this due to low sand, or a cracked lateral? (ive found sand in the bottom of the pool, that's why I checked the return, no sand from that yet though.)
