Great product
Worked perfect for my pool
Good closing kit for my 17k gal pool
I have a 17,000 gal in-ground pool that I typically close from October to April/May, depending on the weather. I always ensure that the pool is very clean and the chems balanced before closing. I typically only use an AquaPill to close the pool and the pool is sparkling clear when I open it in the spring. I decided to try this pool closing kit this year. It looks to have everything you need to close the pool that you see in other kits. I'm not sure yet what the results will be as I will not know until the spring when I open the pool. But so far, so good. This kit does seem a little higher in price than other closing kits on Amazon, so I'm still questioning the value in it.
Easy to use
This kit provides everything you need to winterize your pool, making the process easy and affordable. The chemicals are clearly labeled and simple to use, which was especially helpful since we were closing the pool ourselves for the first time. Given how expensive our pool company’s closing service had become, this kit was a great alternative. The instructions were straightforward, and within an hour, my pool was properly treated and ready for the winter months. The chemicals did exactly what they promised, keeping the water clear and balanced for several weeks after the closure.The only downside was that one of the chemical bottles arrived slightly damaged, though thankfully, nothing leaked. Additionally, while the kit is effective, the price might be a bit high for those with smaller pools. Overall, it’s a solid investment for maintaining your pool during the off-season.
Very easy complete kit
Good size, clear instructions, good price. I guess we'll see how the pool opens but everything I expected was in there
Easy to use
This set comes with everything needed to close your pool for the winter. The packages each have their own purpose and the instructions are very clear and easy to follow. Everything you need is right in this package. I would greatly recommend.
