CPDI Champion 4-Pack Acidblue Muriatic Acid for Swimming Pools & Spas, 1 Gallon Each - Low-Fume pH Stabilizer & Cleaner for Concrete & Masonry Surfaces, Clears Rust & Scale Build-Up

Product arrived quickly, and on the date promised. This muriatic acid is as effective as muriatic acid you would purchase from Leslie's, but for half the price. There is no difference in dosage between this acid and the more expensive acid, and it lowers PH levels as you would expect. I have a 16x24 inground pool, and these 4 gallons should last through the entire summer. Mix a cup in the soap dispenser of a pressure washer and it cleans the concrete deck around the pool like magic.

I cannot use regular acid because the fumes irritate my lungs. This product has no odor and I feel safe using it. It is more expensive but I feel safe using it

This muriatic acid worked well to lower the alkalinity in our pool. It was easy to apply and did not have an odor or splash when applying. We liked that it came in a 4 pack and was a better buy.

Delivered on time. Great product.

Great product but it doesn’t last as long as the regular muric acid that I buy from the local pool store. This is safer and that’s why I will continue to use it. It has no toxic fumes but I still take the same precautions that I do while using any acid product.

Works well for ph control No heavy fumes or vapors. Very stable formula

The product is great for my Ph being too high. Having Amazon deliver this to my door, saves time and money and the pricing is good!

Works well for balancing my pool. Does as described for ph
