Rated 2.5 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Check the date code.... I need to clarify a thing or two. Yes, sodium hypochlorite has a half-life (shelf life). The higher the concentration, the shorter the half-life is. This 10% chlorine will lose half its concentration in 241 days at 80F. Normal bleach (Clorox) is typically 6-8.5% and will thus degrade more slowly. I called the company to verify how to read their date code. The first two digits are indeed the year (14=2014). The next three are the day of the year (365=Dec 31st). Thus, pick the freshest you can find. And, 10% is not a low concentration. It's a pretty decent one for a consumer product. Chlorine is a very potent chemical. That's why we use it as a sanitizer. The government won't let untrained people handle highly concentrated chlorine solutions for good reasons. I also compared the price of this product vs Clorox sold at warehouses and it's extremely competitive. May I recommend the TroubleFreePool website for more thorough discussion on pool chemistry? It's been invaluable to me. June 28, 2014
Rated 4.0 out of 5.0 by Good value Looked around on the net and retail ,this price is hard to beat At $6.86 for two gallons ,no pool supply store or chem wherehouse can meet it. August 26, 2010
Rated 4.0 out of 5.0 by Good Value Anyone that has surpassed the cyanuric acid (stabilizer) maximum in their pool will need to use liquid chlorine for a period of time until the water normalizes. This is a good option instead of emptying your pool to get rid of too much stabilizer. Glad to have this liquid chlorine available when I need it, which is now. July 25, 2013
Rated 3.0 out of 5.0 by weak when old This product has a shelf life and weakens when stored and heat even worse. Your can read the date code yyddmm, the first five digits. If it is over a month old do not buy and you will save frustration. Just bought some and it was four months old, calculated with my pool it was a little over 6%. September 3, 2013
Rated 1.0 out of 5.0 by Old chlorine is worthless! As mentioned before, if it is more than a month old, it will have lost half or more of its strength. I found it at my local home Depot ( they must have had over 50 2 packs)-- not a one of them was less than 6 months old. At the full 10%, it's cost effective, but at 5% you'd be better off buying the 8.25% fresh at Walmart. Unfortunately, Walmart doesn't sell the hth 10% anywhere in South Carolina. Using the 8.25% in my 24000 gal pool, it will increase my free chlorine level 1ppm for 89 cents. It's just that to keep it at 3ppm I would be adding ~ 1 bottle/day or $90/month. How Depot needs to get rid of all is Old, and replenish worth fresh every 2 weeks. October 24, 2013
Rated 1.0 out of 5.0 by Weak,weak,weak. I have owned a pool for 25 years and when I added two gallons of this new liquid chlorine Kem-Tek to my pool it only lasted one week compared to the two and a half weeks I was getting with the chlorine they were carrying before. Regardless of what it says on the box, this Kem-Tek is weaker and does not last as long. And yes I am doing the same maintenance. July 11, 2013
Rated 2.0 out of 5.0 chlorine was very weak I have owned a pool for 11 years and when I added one gallon to my pool it only got my chlorine level up half of what I was used too. Maybe the home depot by me had old chlorine but this never happened when I shopped at my east long beach pool supply. December 6, 2012
Rated 1.0 out of 5.0 by Weak percentage I thought I would try this out since the stated strength was 10% and the price was reasonable. Based on my experience the actual strength is probably around 3% so I'm back to good old Clorox. April 27, 2014
