This will be the 3rd year of using this pool closing kit. my pool is 15' x 52''. I do add extra chlorine tablets in the old floats from the last 2 years. I cover the pool with a black tarp. The water is nice and clear the next spring. Good product, reasonably priced.

This pool closing kit exceeded my expectations. Everything arrived together in one box, even though the listing mentioned items might ship separately. The instructions were clear, easy to follow, and made the process simple. What I thought would be an all-day project ended up taking only a few hours, with just a few bottles to pour in at timed intervals. As a first-time pool owner closing for the winter, this kit gave me confidence, saved me a significant amount of money compared to hiring a service, and made the process feel effortless. Looking forward to opening in the spring, but I’m very pleased with how easy and effective this kit made the closing process.

Excellent pool closing kit. Over years I've used several different closing kits. They all produced the same results. The pool pool always looked like the black lagoon at opening. This kit is the only one that has worked so far. The water is cloudy but not murky. Highly recommended.

I can't give this a full review as I've just closed my pool, so don't know what it will look like when I open it. The kit is easy to use. Only issue I have so far is the floater sank when I put it in the pool and is not floating.

Usually we drain our pool and refill it every year to avoid murky swamp water that's ends up being a breeding ground for a cajillion frogs and who knows what else but with the increase of absolutely everything it's just not even possible anymore to drain and refill and we still want to enjoy the pool at minimal cost so we decided to try to close it and leave the water in it. We followed all the instructions and throughout the winter season we had some issues the worst being a couple of holes in the cover that ended up allowed a few branches and leaves to get through so we ended up taping it and hoping it would last until it was time for the big reveal. OMG you guys!!. We just pulled our cover off today and we're absolutely amazed by what we see. We were blown away by how the water is still clear I mean "WHAAAT" I didn't think that would actually be a thing!!. Just WOW. Sooo... We decide to buy the chemicals by the same company to open the pool and that's what we are currently doing now. The whole process of closing was pretty easy and even opening is pretty easy too. We have no complaints and are very happy that our pool will be up and ready in the matter of a days. We are officially customers for life. Now please don't raise the price 🤣
