    • With any product working like it should and claims!
Size: Super – 35k gallons
I had just ordered a pool after not having one for over 20+ years,So I didn’t know about a lot of the new products I just knew what I needed and this opening pool kit seemed to check off all the boxes,It’s easy to use the directions are clear,All I had to do was read which one to start off with,The value of the product was affordable considering what you would pay for the individual bottles and shock packets, I couldn’t believe the prices for the pool products that you just have to have,So far after using this product I have only had to deal with iron from my well, I would’ve liked to have a couple of bottles to help remove the iron out,But I bought some floc and it really helped and the clarifier did a good job, I still have some shock and algacide left since I have been fortunate to not get algae in my pool which concerned me, I would recommend this product to anyone who wants to have what you need to get your pool up and running to enjoy,So for the money it’s a good deal and it worked for me, I am now enjoying a clean and clear pool,But I have to say having the right sand filter and pump will make all the difference in the chemicals working properly, I hope I have helped others considering buying this product by my experience using it, I wouldn’t hesitate buying it again!!! ... show more

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

    • Easy Opening
Size: Super – 35k gallons
We have been using these to open our pool for the past 7 years and we get a great season every time. If you have a lot of trees in your area and a mesh cover you may have to shock the pool a few additional times but this will clear up and open regular winter water conditions with easy to follow instructions. ... show more

    • totally worth it
Size: Deluxe – 15k gallons
This has allowed me to open my pool for about $400 less each year than paying the "pros" to do it. Has given me everything I've needed to get my water chemistry started off properly the past two summers.
