We used this last year and this year to close our family pool. It really simplifies the process and does the job great! One stop shop to get everything in one shot! Keeps the water quality good throughout the off season, algae growth down, and chlorine levels in check so you have a clear pool when you open the following season! No swamp water with this kit!

I have used this closing kid for the last few years without issue. Really easy to use and has ensured an easy opening. I thought I would include some pictures after closing it in late August and opening in early June.

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 🤣

After using it over the winter, this is the clearest our pool has been when opening in the spring.

This is the best product ever! This was the first year that we left our Intex pool up for the winter. We would usually take it down and put it back up, but that was getting to be too much work. I used In the Swim's pool closing kit and I am very happy with the results. When we opened the pool, the water was only slightly cloudy, but no green algae at all. I just used a Chlorine shock (2 gallons chlorine for 8,400 gallons water) and the next day, the water was clear. I will definitely continue to use this product every year.
