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

I appreciate that Aquadoc’s pH Increaser comes in a resealable bag. The particular bag of 10 pounds of pH increaser was a bit dirty, as shown in the picture. There were also some granules in the box, but the product seems sealed and is completely usable. This product is a must if you have a saltwater pool.

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!!

This item is great for bringing our pH up in our above ground pool! Use amounts recommended for your size pool…this bag (10lb) will last for along time for our pool. (26x52). Our water is city water and has lots of chlorine in it.

This works perfect for my new pool! Chemicals were off a little %26 we put this right in %26 it worked very fast! Great product! Will buy more!

Just what I needed. Also this said a week for delivery and came in 2 days.

Worked great to shock the pool. Got it to the levels I needed it. I have a big pool so I needed more than one but still great

I think they’re a terrific product and I’m very pleased with it and I’m very satisfied thank you so much

I used about 1/2 of the bag and the PH came up very good. It dissolved very well and no clumps in the bag.
