    • Great stuff

I just wanted to say how amazing it is to have everything you need for your pool. I live in a rural area so ordering like this is so convenient. The product itself is easy to use and the instructions are very helpful.

It’s time to open the pool for spring. Yesterday the pool was totally Green and gross. We leave the pool uncovered all winter so cleaning it for spring is a job… Purchased the kit for 35000. My pool is 13,500. We won’t get in the pool for another month so it’s ok to add the chemicals we added. This kit comes with easy to read instructions on the order of chemicals and the best part is that it works!!!! I’m really impressed that the pool is blue in one day! Last year we struggled to get it blue at all! I recommend this product for opening the pool for the season! ... show more
