I use this product. I have a 15,000 gallon in ground concrete pool and live in Florida, where we get tons of summer rains. I have no problem with this product. I use about tablet a week and in the summer I add a gallon of liquid chlorine every couple weeks as shock treatment. This product seems to do the job. I do how ever add stabilizer every April and then maybe once during the middle of the summer.

This review is not about the actual product, I am sure it is great. This review is about the need to weigh your bucket to ensure you aren't buying 35lbs instead of 40. I purchased 2 buckets from a pallet that had obviously been picked through some. I took a couple buckets that were still on the pallet and I thought had been unmolested. Loaded them in the cart paid and took them home. Upon unloading them together for the first time (one in each hand) I could tell one was lighter. When weighed on my home scale is just over 33 lbs so including the bucket I was shorted probably 18-20 tablets at more than a buck a piece. If it weren't such an inconvenience I would have loaded them back up to exchange them but I am chalking it up to stupid tax. Next time I will make sure to do a better job of judging the weight.

I had previously purchased chlorine tablets at Sam's Club and had been very happy wwith them. This year I started having trouble keeping chlorine levels up and the pool clear. After a lot of frustration and a little research I learned about stabilized vs unstabilized chlorine. Apparently Sam's changed their formulation and this unstabilized type is better for indoor pools but will dissipate quickly outdoors unless you add stabilizer separately.

Everything was as advertised, I just wish they had the 4n1 in the same quantities...

Easy to use. Free delivery!

Glad you had product as there is a shortage at this time

Product works well and the available chlorine it’s what we look for in our tablets
