Saw what I am pretty sure was sand in pool. Put sock over return, no more sand or sediment so I replaced lateral assembly. Did not see anything wrong with old assembly, but replaced anyways. Less suspected sand but still a good amount around with the run time of about 6 hours. I figured this was just environmental (sediment) and not sand. The last two days I have ran the pump just enough to circulate the chlorine. Hardly any suspected sand/sediment in the pool, maybe half a tea spoon. So with the pump barely running, but with the same environmental conditions such as wind etc, I am seeing nearly 99% less sediment in the pool. So I believe something still isn't right with the filter and what I am seeing is in fact sand. What else could it be?
