  • Good pool product
Size: (Pack of 1)
This product does help reduce ph in the pool.

  • Price is right
Size: (Pack of 1)
The price is right and it does the job. It is cheaper then the big box and pool stores near us.

  • Quick results.
Size: (Pack of 1)
If you have a pool and need your PH down this works wonders. Not too pricey, doesn’t cloud the water. It seemed to dissolve fairly quickly. I did disperse it right at my jet and had no problems with it. No algae and perfect water levels. Within about 4 hours my PH was in the perfect range.

  • Generally works well.
Size: (Pack of 1)
I've used this product for a few years. It's a good balance between size (not a huge bucket) and price (sometimes smaller sizes are much more expensive). Only problem I've had is they sent one package that was alkalinity increaser instead of PH reducer and I didn't realize till after I started poring it in. ... show more

  • Works Well, but Packaging Needs Improvement
Size: (Pack of 1)
This product definitely works, in fact, I think it’s more effective than some other pH reducers I’ve tried. The issue is the packaging. The bag doesn’t zip back up properly and leaves gaps, which means product can spill out. Great formula, but disappointing design. For now, I’m going back to what I used before. ... show more
