  • I’ll never use another brand of chemicals!
This stuff is amazing! I’ve had salt pools as a kid and pools we used other brands of chemicals with, and this stuff works amazing! We have 1 chlorine tab and the oil absorber and that’s all we have used in 2 weeks and it isn’t a bit of cloudy! We covered it for 2 days and haven’t covered it since. I’ll never buy another brand of pool chemicals again. ... show more

  • Never had a pool before? ----> READ ME!
It's ok.. with loads of AI help if you'd never taken care of a pool before... also, double check with more than 1 AI, Grok tried to kill us lol I got the basic opener. It says that it's got enough stuff to keep it goin' the whole season. It doesn't. Even if you have a smaller pool, it's only enough to open it the first week. There are enough chlorine tabs to go the season but not the rest of the stuff they tell you; you need to keep up with, only comes with 10 tester strips and the little squares come off in the water. Also the measurements are off. You'll need to math lol ... show more

  • DO NOT BUY
These did absolutely nothing to clean my pool. It cleaned the surface of water. But everything else was exactly the same as it was before I put these in. The algae was totally up and down the pool walls. The instructors don’t specify the gallon ratio. DOES NOT WORK, my wife says the smell lingered the back yard. ... show more

  • great starter package
This was a great starter kit. We got our first pool and I was so lost on where to even start. It was a great package to get me started. There are a few things that I am not sure if I will end up needing them but I am glad I got it to get me started.
