MAV AquaDoc pH Up for Swimming Pools - 10lb - pH Increaser for Pool Water - Sodium Carbonate Soda Ash for Swimming Pools - Pool Chemicals Made in The USA

This product is a must‑have for your pool supply stock. Sodium Bisulfate pH Increaser works quickly and effectively to increase your pH, helping keep pool water balanced and comfortable. I used this product throughout last season and was very impressed with how well it performed. It dissolves fast, with results quickly after adding it to the water. One great feature is the QR code on the bag, which is a great resource if you need additional guidance or information. The back of the package also includes a clear and helpful dosing table, making it easy to add the correct amount of product. Overall, it’s a high‑quality, reliable product that does exactly what it’s supposed to do. Made in the USA and definitely something I’ll continue to keep on hand for regular pool maintenance. Great product!

This is a necessary item for pool owners and is at a good price. The shipping was fast too, which is appreciated!!
