Incompatible Pool Chemicals

When adding chemicals to your pool, it is important to avoid adding certain chemicals with others that may have negative reactions in the pool. When introducing any chemicals into the water, use instructions on each individual product to see when and how they can be added to avoid any conflicts. Make sure the pump is running between chemical additions, as that will help disperse the product.

Do not add a hardness increaser like Leslie’s Hardness Plus and a sodium bicarbonate product like Leslie’s Alkalinity Up too close together. These two products will react and cause cloudy water and small solids to appear in the water, along with an increase in scale on pool surfaces and equipment. This effect will also been seen when Leslie’s Hardness Plus and Leslie’s Soda Ash are added together.

Also avoid adding a clarifier like Leslie’s Ultra Bright with a sequestering agent such as Leslie’s Stain and Scale. Your water will cloud up very quickly and will not be able to be cleared with filtration.

When dealing with chlorine, there are a few things you need to watch out for. First, never mix a trichlor tablet (EX. Leslie’s 3” Jumbo Tabs) with a calcium hypochlorite product like Leslie’s Power Powder Plus. A dangerous fire or explosion could result from putting these chemicals together in the water.

You should also never add any form of shock with metals in the water. A drastic increase in chlorine or sustained amounts of chlorine in the water will cause staining if there is copper or iron present in the water.

When using an enzyme product, avoid adding shock before or after the enzymes because the shock can destroy the product you just inserted into the pool.

Perhaps most important note of all, never add chlorine and muriatic acid together in the pool. This creates a dangerous toxic gas that can have severe health consequences if inhaled.

If there is ever any question as to when products can be added, always follow the directions on the back of the product and talk to a local Leslie’s professional.
