SeaKlearAquaPill - WinterPill 2 ¾

Worked kept my pool water crystal clear over the winter under my pool cover. That's why I've bought again for this winter.

In early October I over chlorinated our 10,000 gallon above ground pool, threw this Pill Pool, and then winterized and covered it. Here we are 7+ months later. I took the cover off, and the water is clear and nice with just a touch too high chlorine. Honestly, the chems are close enough that I could have gone swimming immediately after removing the cover. 100% chance I will buy this again this fall, but I probably won't over chlorinate my pool too much this time as the pill seemed to handle it just fine.

We have been using this ball for years! It’s one step and super easy! Way cheaper than all the individual chemicals we used to buy.When we open our pool in the spring, our water is clear. Makes opening the pool much easier.

Tossed this in the above ground pool in the fall and when i opened the pool in the spring the water was super clear. No algae or mould. Bought a second one for this upcoming winter.

I closed down our pool yesterday. Went through all the work of draining and removing all steps and equipment, got the pool cover stretched out over it and was ready to go. Went to retrieve my Amazon package with this item in it only to find that it was leaking all inside the package. I had to go ahead and put it in the poo as I was ready to strap the cover and call it done. Upon further inspection the cap where the fluid is supposed to come out was cracked. All of the fluid may be out by now, I'm sure it won't time release as it is supposed to. I was excited to use this product for all the rave reviews, but am disappointed that it may not last all winter. Only time will tell - I wish I would have had time to exchange but I was already to far in the pool closing process. :(5/6/23 Update: Just opened the pool. Clear as a bell!! Did what it was supposed to do! Will purchase again.
