Acid Blue Muriatic Acid by CPDI - Swimming Pool pH Reducer Balancer Buffered, Low-Fume - Case (4 Gallons), RE-GHJK-34

Not sure how they do it, but this is the same strength as the nasty stuff, but it has far less fumes and doesn't burn skin quite as quickly if you get a little splash on you (still wash it off quickly, but not quite the same instant burn). I thought this might be more dilute, but it's not. Works great. I use a lot of it because our tap water pH is quite high so I'm constantly adding acid to balance it out.

I only use this to lower my PH in a salt pool and it is just as effective as standard muriatic acid at a substantially lower price. It has less smell and doesn't seem to burn the skin as much after an accidental splash although I did wash it off immediately. Not sure how it works for cleaning purposes but for pool use, 5 stars!

First time swimming pool owner here. One year using it. Never bought another brand, and my tests confirm it is working very well. Going to the second pool season with this one again.

I have gone through a few gallons of this stuff on a new gunite pool. Works just like the the other muriatic acid but does not produce any noticeable gas. The other stuff I was using would burn your nose hair out if it was humid outside.

I live in Texas and this product has been a game changer for my pool. I do my own maintenance and balancing. I recommend this product if you a pool in direct sunlight.

Pool looks great.

Works fine

I have had a pool company working on my pool for 6 weeks. They have been out 5 times. Out of that 5 times they have never been able to get my pool clear. I was told to add muriatic acid to my pool, so I ordered this product, "Acid Blue Muriatic Acid". Wow!! The next morning the water was so clear and beautiful.
