Description
Bromothymol Blue is a pH indicator to show the pH balance of water.
Directions: For cold and tropical freshwater use. Rinse out a clear jar or vial using your aquariums water. Add 10 drops to 15ml of water in a small container or vial. Shake until the Bromothymol Blue has mixed with the water. Do not cover the top of the container with fingers as this can lead to a false reading. See reference chart on bottle for pH level.
When changing the pH balance of water it will have better results and be safer for fish to do it gradually, testing every day and then adding slight amounts of pH Up or pH down every second day.
