This is a Pool Winterizer. Bottle is 16 oz and it’s a 3-in-1 enzyme formula to insure a worry-free experience for both pool closure and reopening. This will keep your pool pristine through the winter months. By using this pool winterizer closer, you’ll reduce the need for extra clarifiers. This 16 oz bottle is all you will need. Wait at least 24 hours after shocking your pool for the winter before adding this pool winterizer closer. After pouring the whole bottle in the pool, just cover it and wait until next spring. This is a great value for your money. I will be back after the winter to update if needed.

We'll assume that you own a pool or jacuzzi. That or are planning to gift this to someone. Pros to this particular winterizer is that it helps prevents algae and bacteria. It should also maintain the water chemistry until spring. Try not to use it as a substitute for winterizing measures like draining or covering.

Worked like magic I was very happy with this product didn’t need to put much and it cleared the water very fast. I must say I had offcourse to clean first the debris from trees and leaves but the water looked nice and clean after I put this product in.

This is a bottle of pool closing kit, but it seems strange that everything you need is in one bottle and it doesn't list what is included. In the past when we get a closing kit, there are multiple chemicals. This does have you shock the pool first, let that run through the filter, then drain the pool below the filter line, add this and put the cover on. Note that one bottle is likely not enough for a regular above ground pool. It is easy to use and convenient however.

This is a must have for any pool owner. It's made from quality ingredients that are listed on the label as well as easy to read and follow instructions. It's super easy to use and works great. I used this same product last year when closing up my pool so I know it works great. If for some reason next spring when I open up the pool it didn't work I'll come back and update this review.

I have not been able to use this chemical solution yet because we haven't closed our pool for the summer. However, I compared the ingredients to the closing chemicals we used last year, and the active ingredients are nearly identical. This bottle is the same size, but less than half of the price! Very happy to find this chemical solution, and I will update this review after closing the pool in 4 - 6 weeks!

This pool solution is all you’ll need to close your pool for winter time. It has easy instructions and is to use. Save money with buying this solution instead of many different products.
