Why are swimming pool tiles mostly blue?
Actually, can you tell me how to maintain the pH level in a swimming pool?
To maintain the pH level in a swimming pool, you can use chemicals like pH increasers or pH decreasers. Testing the water regularly, especially after periods of heavy use, and adjusting the pH level as needed can also help maintain a safe and healthy swimming environment. Do you have any other questions on the topic?
