When a pool company closed my pool last year, they took the skimmer door off my IG pool. I opened my pool this weekend. I wasn't sure how it goes back on so I asked a guy in the biz and he mentioned the door is better left off on my pool because I'll see less junk on the surface by the skimmer. I tend to agree with him as I do see less so far around the skimmer. Is this ok to leave off? I do have to clean my skimmer basket more often it seems but I also cut down time skimming the pool.
