Should chlorination be off when you add pH plus in salt water pool?

It is generally recommended to turn off the chlorinator when adding pH increaser to a saltwater pool. Here are a few reasons why:

1. Chemical Reaction: When pH increaser is added to the pool water, it can react with the chlorine present in the water, leading to the formation of unwanted disinfection byproducts and reducing the effectiveness of the chlorine.

2. Chloramine Formation: The reaction between pH increaser and chlorine can result in the formation of chloramines, which are less effective at sanitizing the pool water and can cause eye and skin irritation.

3. Equipment Damage: Adding pH increaser while the chlorinator is running can cause damage to the chlorinator cell due to the high concentration of chemicals in the water. The increase in pH levels can also affect the accuracy of the pH meter and the overall operation of the pool system.

4. Safety Precautions: It is generally safer to turn off the chlorinator when adding chemicals to the pool to avoid potential accidents or chemical reactions.

It's important to follow the specific instructions provided by the manufacturer of your pool chemicals and equipment to ensure proper and safe operation of your saltwater pool.
