10-Pack of Pool Skimmer Socks Reusable – Excellent Savers for Filters, Baskets, and Skimmers – The Ideal Sock/Net/Saver to Protect Your Inground or Above Ground Pool, Debris Leaves Catcher

We have an inground pool and it has a retaining wall around three sides of it. Opening the pool is a chore cause it’s always got a lot of dirt in it. These help so much to get all the fines out of the pool. Last year I ran these about half of the season. This year I used them for the majority. I think these help tremendously with keeping things out of your pump basket and keeping your main filter cleaner. I have a normal sand filter and I’ve only had to backwash once this season. In the past I’ll backwash three or four times after the initial opening. It’s basically a pre-filter for your pump and main filter. You might have stuff get in through you main drain but the skimmer will catch most of your debris. It’s a little more of pain to keep them clean or get them clean and they might last a couple of weeks but I’ve used one for about a month with just a few small holes. Changing them every couple of weeks is probably ideal depending on your set up. Great for getting and keeping your pool clean.
