## Features

- PH Decreaser for Pools: Maintaining proper pH balance is key to ensuring healthy pool water. If your pool has high pH, it impacts the effectiveness of chlorine. Water with a very high pH causes skin rashes, cloudy water, and scaling on pool equipment.
- Safe Formula: Our pH decreaser for pools & spas is made with Sodium bisulfate, it comes as dry granules and is considered much safer to handle than muriatic acid. This dry powder is easy to measure, quickly dissolve into your pool, and create less of a mess than their liquid counterparts. This alkalinity decreaser for pools and hot tubs will help balance calcium hardness. lowers pH and the total alkalinity of your pool, hot tub and spa. Guard your pool against poor health and calcium hardness.
- Improves Pool Health: On the pH scale of 0-14, pools & spas should be between 7.2 - 7.6, ideally 7.4. A pH in this range will allow sanitizers to work effectively, prevent scale build-up on sensitive equipment, increase Chlorine effectiveness while stabilizing other pool chemicals, and reduce eye & skin irritation. Less than 30 oz. of our formula works on 10,000 Gallons of water.
- Easy to Use: Measure the pH of the water with a reliable test kit or strip. Use the table at the back of the product to determine the correct dosage to add to your pool. Broadcast this product evenly over the entire water surface and keep the circulation system on. Re-test water after 4 hours and, if needed, add more product. Do not add this product into the skimmer, near underwater lights, or metal ladders
- Sodium Bisulfate: Reduce the pH levels of your pools, spas, and hot tubs without any side effects. Our pH reducer is a safer and less corrosive alternative to muriatic acid. It helps other chemicals work effectively by correcting water chemistry & re-establishes an ideal pH level to prevent skin irritation and equipment damage. Our Sodium bisulfate pH reducer is easy and safe to store.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, glad to find in granules
*by B***M on July 13, 2023*

The first brand I bought of pH reducers came in a liquid. Yeah. It took the whole bottle of liquid to lower my tub to the correct pH, due to our water source. Luckily, this comes as a powder, which goes much further, which saves me money. Awesome!

### ⭐⭐⭐⭐⭐ Worth it.
*by L***E on July 1, 2023*

Don’t waste your money on those expensive ph minus chemicals. This did the trick for a fraction of the cost and I hardly used any. It’ll probably expire before I use it all. Excellent product.

### ⭐⭐⭐⭐ Easy to use
*by T***. on July 27, 2023*

Works as advertised does a little goes along way.
