SeaKlear AquaPill WinterPill Pool Clarifier and Enzyme up to 30,000 Gallons 91222APL

Works like it claims to, my pool is always clear when opening! Easy to use, just puncture and toss in before covering for the winter....perfect.

Good value, I used this last winter and my pool was still crystal clean this spring!

I have used this item for the past two years and am pleased with the results. Pool has to be at the right levels when closing.

Still new at this pool chemical balancing thing but tried this out this past winter. When I took the cover off the other day the pool although a touch cloudy ( when the water was tested the Ph was high >8 and the chlorine very low .19 so I am sure that was the issue and after correction it was clear ) but it was not at all green which was my fear. So I will use it again this coming winter.

I was afraid to take the cover off the pool because I was expecting green water. It is crystal clear. There are a few bugs on the bottom but that's easy to clean up. The winterpill really works. I'll definitely use one again.

Not sure if it was this or just beginners luck but opened my pool thid spring and it was crystal clear.I'll be using again next fall!

This worked the year before last but this year it didn’t seem to work as well but would buy again, could of been my fault.

Arrived on time, working good.
