DO NOT add hydrochloric acid to the pool while the pool is being used.
It is best to wait at least 30 minutes to an hour after adding acid to your pool before you swim in it, this will allow the acid time to mix in with the water.
ALWAYS ensure the acid is mixed thoroughly with water in a bucket before adding it to your pool and REMEMBER always add the acid to water, never add water to acid.
To dose additional acid using the Naked pH Controller please see instructions HERE.
