I typically order my pool start up kit from Leslie's but this was cheaper, in stock and free shipping. It worked great - pool was crystal clear after going through the process and running the pump 2 days. Step by step instructions easy to follow. I will be checking in the Fall for a similar pool closing kit from Doheny's.

The media could not be loaded. This kit took all the guesswork out of opening my pool for the season. As a first-time pool owner, I wasn’t sure what products I’d need or how much, but Doheny’s Ultimate Pool Opening Kit made it easy. The instructions were straightforward, the chemicals worked exactly as promised, and I had my pool clear and swim-ready in no time. It saved me money and stress by bundling everything together, and I’m grateful for how beginner-friendly it is. Highly recommend for anyone who wants a no-fuss, effective pool opening!

Worked ok. Water was still extremely cloudy afterwards. I’m not sure the previous owner closed the pool properly.

Best pool product. I’ve been using Dohenys products for 20 years. I will never stray. Pool stats clear all summer and is clear when open.

I'm giving 5 stars because the directions were clear, you just follow the steps. There's no guesswork. I haven't seen much results yet, but thats because the water is extremely bad from not being opened in a few years. I anticipated I might need two kits, but sometimes it takes a couple days for a surfactant to work. It's pretty murky. I'll keep draining about 25% and adding it back fresh, combined with these kits (skipping a few of the steps because I don't need some of the levels to be 5x overkill), until I win. BUT, if I didn't have those problems, this kit would be a gem. If you just have a normal seasonal situation that doesn't look like Chernobyl, this is the stuff.
