Interpet Aquarium pH Down Adjuster
If the water in your aquarium has a pH of above 8.5, then this is the water treatment for you. It gradually reduces the pH level to a safe level to prevent pH shock, and adds essential buffers to keep the pH level stable.
This clever treatment gives you extra peace of mind with the built-in safety mechanism which prevents pH levels moving out of the safe zone, even if you've accidentally added too much.
Use for treating aquariums with a pH of 8.5 of higher.
