Rx Clear 3" Inch Stabilized Chlorine Tablets | 35 Pounds | Individual Chlorinating Tabs for Sanitizing Swimming Pools | Long Lasting, Slow Dissolving, and UV Protected

I still consider myself a fairly new pool owner even though I am in my third summer season. I have slowly weaned myself away from the pool company and now take care of pretty much everything myself. The last step was to move away from the expensive chemicals they sold me, including getting those same name brand chemicals cheaper on Amazon. After reading the reviews, I decided to give these pucks a try.I was previously using the Bioguard Smart Sticks. I liked that they dissolved slowly and not much at all unless water was flowing over them in my skimmer basket. I was concerned that these pucks would dissolve even when water was not flowing over them thereby creating a high concentration of chlorine in my skimmer basket when the pump was off. I am pleased to say that they dissolve very slowly and also seem to require running water to dissolve very quickly at all. I initially put a couple in my skimmer basket and then a couple in a floater I have. The ones in the floater hadn't dissolved hardly at all after a week. The ones in the basket were nearly gone after a week. That was exactly the result I was hoping for.Most of the pucks arrived in one piece although a few were broken. I know the broken pucks work the same, but the surface area is different which means they dissolve at a different rate. I prefer to know the rate of chlorine going into the pool (after tracking chlorine levels and number of pucks used). I tend to be very precise in my maintenance (and in life). Overall, I think the packaging is sufficient and it is expecting too much for every puck to arrive intact. The vast majority were and that is good enough for me.Lastly, this is true for any pucks of stabilized chlorine, but you really need to monitor the stabilizer if you use these. Chlorine gets used up constantly but the stabilizer doesn't. It is possible to end up with too much stabilizer in the pool and that can reduce the effectiveness of your chlorine requiring you to use more chlorine. The more pucks you put in, the more stabilizer gets added thus creating a vicious cycle. My plan is to use these in the beginning of the season when my stabilizer is low after lowering the water level during winter. Once the stabilizer level gets to the high side of normal, I will switch to liquid chlorine. Liquid chlorine is more of a pain, but it allows me to better control my chemistry.My last observation about these pucks is that their pH is pretty low at 2.7. I like this about them. When I use liquid chlorine, my pH tends to slowly rise over time. When I started using these pucks, my pH would go down over time. Why do I like this? I like it because I can raise pH without the use of chemicals. I cannot lower pH without using chemicals. I have a submersible pump to throw water into the air which raises pH when needed. I have also been able to adjust the return nozzles to break the surface of the water to counteract the slow pH descent creating a balance so I don't have to use the submersible pump. The bottom line is that it gives me more control and the ability to create a balance. If you are not familiar with aerating your water to raise pH, I highly recommend you read up on it.Overall, these pucks are an excellent buy with great value and I couldn't recommend them more.

I don't blame the company for the price. I blame Biden. This product used to cost under a $100. Now, it is almost $250. Unfortunately, if you own a pool, you need to chlorinate it. The product works, but I HATE the price.

I typically order at least one or two 50 LB buckets per year. I've purchased from a handful of different vendors on Amazon, some good, some better than others. I've been buying my tablets online from Amazon for about 5 years now.The reasons these are my favorite:• Each tablet is not only individually wrapped, they're wrapped with a sturdier plastic. Other vendors' tabs have a 'softer' wrapper, which tends to tear open in the bucket. The first thing I noticed with this was, when you open the lid, you're not hit with a crazy-strong chlorine blast (I'd typically hold my breath and look away while opening the lid).• I haven't found a single broken tablet yet (not a deal-breaker if some are, but every single one has been pretty much intact).• They last/do the trick.The wrapper-style and lack of smell, are my key takeaways though -- would definitely recommend if you use 3" tabs in your pool!

I've used these for three summers. My filter runs 8 - 12 hours/day depending on how hot it is, the pool is skimmed daily and the Polaris runs when the filter runs so there are rarely leaves for any length of time. I'm the only one who uses it, except for some friends on occasion. That said, I have not had to add any other chemicals at all for the past two summers. I shock it when I think about it every month or so, or if we've had a lot of rain. Two summers ago, I had an algae problem when I had to use some stuff to get rid of it. I also scrubbed everything and even cleaned the ladder with Clorox and finally got rid of it...we also had a lot of crazy rain that summer. I believe that is when I first started using these tablets.I merely keep the floatie filled with these tablets, usually at least four and five, if I can fit them. It usually takes about a week for them to dissolve if the temperature stays in the 80s. When the temp goes into the 90s, I probably have to fill it every 3-4 days. My first order was June 2018 of 50 lbs., and 50 lbs again in June 2019, which lasted me two summers. I am just ordering another 50 lbs. at the end of 2020 summer. Needless to say, I highly recommend these.

Broken tabs are THE issue when dealing with 3" tabs. They are easy to break both at the factory and (mostly) during shipping. It does not seem to matter if the tub is small or a massive 50 pound tub...it is pretty common to find broken tabs in both. It also does not matter if you buy them online or in a store. Its so common that the manufactures have gone to putting little notes in the buckets stating that its ok if tabs are broken...they are still good to use. I disagree. There are issues that come with broken tabs. The more broken they are they quicker they dissolve in the water. You want uniform delivery of the chlorine, otherwise you would just use powder. Sometimes the tabs are so broken that you basically just have powder. Another issue is the broken and/or powdered tabs are messy and more difficult to use. So YES, it does make a difference if the tabs are broken or not. In this case my 50 pound bucket was completely intact. This was my first time to use this brand so I don't know if this is common or uncommon. I have seen posted pics of broken tabs here in the reviews, so I know it happens. The question is are those the exceptions or the rule. In any case, my bucket arrived in great condition and because of this I will buy them again!

i never knew these existed till my son told me about them. He buys his locally but i could never find the place open when i went to town so i looked on Amazon and found these. They are great lower priced than the local ones and my pool is clear and clean. So happy with this product a great value and a clear pool!!! will buy again and again.
