5.0 out of 5 stars Very good product.
Reviewed in the United States on July 22, 2024
I recently purchased this product. I try to find what's on sale and a good price. I've purchased different 3 inch tablets in the past from different manufacturers and I decided to give these tablets a try. I was just finishing up the chlorine tablets that I had previously purchased, and I was adding shock once a week to keep the algi under control. It seemed like I was brushing the sides of the pool daily to get rid of the algi.

When I started using these tablets it seemed that the agli was not growing back. The temperature outside was the same but no algi. I've been using these tablets for about 3 weeks and my algi problem is gone. A really great product for the price.

5.0 out of 5 stars Best 3" Chlorine Tab 50lb- Better IW, Better Pack
Reviewed in the United States on July 25, 2024
All mail order chlorine tabs are individually wrapped. This is MUCH better than my last bucket of In the swim brand. The Pucks are harder, none broken so far, (inner wrap is tight to reduce movement during shipping) side by side test in skimmer lasts exactly 1 more day before dissolving. (4 vs 3) The pouches are much better too, thicker and clear vs translucent and thin with dust. No dust in these. The fact that they were cheaper on top of all this is what prompted me to write this review.

5.0 out of 5 stars I'm Impressed

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.

Perfect chlorine tablets for your pool to help fight bacteria growth and keep water cleaner. I use a handful of tablets in a floating chlorine holder. They do dissolve in a slow release consistency lasting hours and days. Tablets are good size. Each tablet individually wrapped. Package arrived within estimated delivery. Happy with purchase. Fair pricing for bucket of tablets.

5.0 out of 5 stars By Far the Best Pricing and Packaging!

You will NOT be disappointed with this purchase. From the delievery (via Federal express that arrived EARLY) to the packaging (a locked/sealed hard plastic bucket/container, with each tablet individually wrapped in a thick plastic, but easy to tear open each individual tablet when needed) and NOT one tablet was cracked or broken (this is very rare). We've purchased these from big box stores to our local pool supplier. Not anymore. Hands down, you cannot beat this product from the PRICE, delivery, packaging and quality of the tablets. These tablets (3 inch) do an excellent job in our inground pool. We place them directly into our skimmer basket (usually 2) and also into our floating chlorinator (usually 3). Needless to say, a very pleased customer that will also be a very happy repeat customer going forward! Thanks again!!
