This morning I found sand and small plastic particles in my pool, where they were located was right under a return in the shallow end. It looks like they were pushed out the return and landed right there on the pool floor. I do NOT have a sand filter. I attached a photo of the sand and the particles. I found a few particles on my step in the deep end under a return as well, but not many. Anyone know what could cause this? I’ve been wondering if we have a leak over the last few weeks but it’s been very hard to tell. Thanks in advance for any help!
