Ok, thanks. I couldn't resist checking the sand, and sure enough, the sand I blew out on initial backwash caused me to be low on sand and the sand that's in there isn't anything like the old I took out, the new was more like play sand. I wanted to remove my lateral assembly but on my s200 the variflow comes in on the side and I couldn't get the bulkhead fitting off. Best I could tell laterals look fine. So with proper sized filter sand and some DE I hope to get my pool clean
