I have a sand filter that the original paperwork shows it be a #200 capacity. I have put #150 In because I couldn’t find the specs now I have sand coming into the pool looks to be about 3 lbs. I checked all the laterals when I cleaned the old sand out and us great care As I reassembled but now this. I have vacuumed it out and it returns after backwash and rinse. I do notice it the sight glass as I rinse I see sand but not during backwash

Did you fill the filter half way with water before dumping the sand in? Was the sand dry and did you use filter sand?
