Huge Sized Chlorine Tablets!!!

[This review was collected as part of a promotion.] Normally when I buy chlorine tablets for my pool they are tiny!!! I literally have to replace them about every three days. Not these!!! They shocked me on how huge they were! I love it! I put one in my skimmer about a week ago and I just looked and it's still there and will probably last a few more days! Definitely worth the money and saves me the time of having to go outside and check it. It has made my pool water beautiful and clear! I checked the chlorine levels a few days after putting it in and it was exactly where it was supposed to be! Great deal!
