The discoloration of swimming pool water mentioned here specifically refers to the change in color caused by the oxidation of excessive metal ions in the pool water by oxygen in the air or chlorine disinfectants. Originally clear swimming pool water may suddenly turn green, reddish-brown, or black due to the presence of corresponding copper, iron, or manganese ions in the water. If multiple oxidizable metal ions are present simultaneously, the pool water can display various unusual colors.

When the swimming pool water has already changed color, you can choose Color Remover developed and produced by BOWS™. It can remove the oxidized color displayed by the pool within one pool water circulation cycle (generally 4 to 6 hours), making the pool water clear. Based on experience, adding 7 to 10ml of Color Remover per ton of water can solve the problem of water discoloration.

The standard dosage of Color Remover should be calculated according to the formula:

Standard dosage (ml) = Metal ion concentration (mg/L) × Total water volume (T) × 12.8

When treating discoloration in swimming pool water, it is necessary to simultaneously add 4 grams of Enzyme Clarifier per ton of water. It can help filter out excessive metal ions in the pool water, preventing the pool from repeatedly experiencing discoloration.

If the swimming pool water appears black, please follow these steps for treatment:

Step One, add TCCA chlorine disinfectant to adjust the free residual chlorine in the pool water to above 3.0ppm.

Finally, keep the swimming pool filtration system running for at least one cycle. Of course, the longer it runs, the better the water discoloration issue will be addressed.
