great for opening the pool
I recently purchased HTH Brilliance Cal Hypo Chlorine Tablets, and they are absolutely perfect for opening my pool this season! These tablets are super effective at keeping the water clean and clear right from the start. Each tablet treats a large volume of water, which makes it easy to get everything balanced quickly. I’ve seen a noticeable reduction in algae and bacteria, and the water feels great to swim in. If you're getting ready to open your pool, I highly recommend HTH Brilliance. It’s a must-have for pool care!

Avoid using In tri-chlor feeder
I tried to use this in a Tri-Chlor feeder thinking it was just another tablet...wrong! Perhaps I should have know that but it was a disaster. Eventually, these tablets clogged my Pentair unit completely leaving a mushy residue inside. I managed to clean it out with effort. So, this might be a great product used some other way but not in my system. To be fair, the container says to use the product in a Cal Hypo feeder but I only noticed that after the fact and those feeders are 3-4 times more expensive. So I continue on my quest to find a convient, CYA free approach.

when i put in my floater, inchecked the next day and it was all just crumbles. i easnt happy with this product at all. do NOT recommend
Hi Sarah, thank you for sharing your feedback. Please know that it is greatly valued and we apologize for the delay in response. Technical difficulties prevented us from seeing your review when it was posted. I'm sorry to hear the tablets did not perform as expected. Because these tablets are calcium hypochlorite based, they do dissolve quite differently from stabilized tablets, and they must be used following the label directions, especially concerning the method of application, to get the intended results. Please give us a call or chat so we can have a better understanding of your experience with the tablets and help you get this product to work as designed! You can reach us at 866-484-7665 or chat with us at hthpools.com. We're Here to Help!
