Would Recommend[This review was collected as part of a promotion.] We currently moved in has a ground pool and the balance is kinda hard to keep In range ,especially living in the south. I have use several products with some luck . I couldn't wait to try this brand and I can say after few days of use I noticed a big difference. The only thing is it doesn't come with measurements up but I was able to use one from a previous brand. I will keep using this product and update my review later.

Did what it was supposed to do
Would Recommend[This review was collected as part of a promotion.] Finally had a chance to use the chemicals when we noticed a ph issue with our pool. I put the chemicals in water first - just as the instructions said. I then poured it into the pool and tested. It took a bit longer than I expected to see the change in pH but it finally did.

HTH® pH Down, 7 lbs.
Would Recommend[This review was collected as part of a promotion.] My pool is around 35,000 gallons and I ended up using about 3 pounds of HTH ph Down to service my pool. Within a few hours, it reduced my ph levels to within range. The product was very effective and performed as advertised. It dissolved in minimal time and dispersed evenly to address the ph issues. The product was also easy to handle and store. The product is easy to use and you do not need to pre-measure, it can be poured directly in...

pH Down works!
Would Recommend[This review was collected as part of a promotion.] After a recent pool remodel of our in ground pool it became necessary to closely monitor our pool chemistry. The pH frequently needed to be adjusted down and HTH ph Down works well. It does also lower the alkalinity so if my pool water alkalinity was already on the low end of recommendations, I adjusted that up first and then waited a day to bring down the pH. The bag specifies how much is needed for each pool size. I previously used liquid mur...

Worked great
Would Recommend[This review was collected as part of a promotion.] I really liked hth ph decreaser . It worked great on lowering the ph level to 7.4 instead of at 8 it was always stuck at. I liked how easy it was to measure and use and how it didnt leave a foam on top and dissolved all the way so there was nothing left behind to sweep up. Works great for large and smaller sized pools.

Good company
Would Recommend[This review was collected as part of a promotion.] I'm really liking this company. The decreaser is a really good product. It's not too much chemicals for the pool and helps reduce stains and build up. I've never had skin irritation dealing with pools so I'm not sure about that.

Worked great.
[This review was collected as part of a promotion.] I have a large pool. Very Large. Approx 50k gallons. According to my calculations, I have to use this whole container for my pool, and it worked perfectly. Dropped my pH into range (it was over 8.0 prior to using). I really liked the container. Better than bags, or buckets, or muratic acid. The granules dissolved easily. I didn't have to sweep. I think muratic acid still comes out cheaper though, so you lose a point on value.
