Foaming in swimming pools and spas can be caused by detergents, soaps or shampoos in the water. This could have happened after cleaning the swimming pool surrounds or if a bather enters the pool or spa without rinsing off shampoo or other skin products.
Foaming can also occur in swimming pools if shower water from the changing area is allowed to drain into the pool. It should be noted that certain detergent-based products such as patio cleaners are incompatible with swimming pool water and they should be kept well away from the pool area.
Also, some pool or spa chemicals, such as algaecides and water clarifiers can cause foaming when added in excess.
Action to be taken:
To reduce concentration of algaecides and/or water clarifiers
To chlorinate (oxidise) out detergents
WARNING: Do not mix Fi-Clor Superfast products with any other types of chlorinating compounds (even other products in the Fi-Clor range) either in the dry state, or in the skimmer. Fire or explosion may result. If using with other products, dose them separately into different areas of the pool.
To use a No Foam product (Spas only)
Apply this product directly to your spa water whilst the spa pump(s) are turn on, to aid distribution.
