Nulife pH down will allow you to decrease your pH as required.

Approx. 4mls per 100 litres of water will lower the pH level by one whole unit ( i.e. from 6 to 5 ). This is a rough guide as each situation is highly variable.

When first using this product use small amounts (i.e. one drop at a time) and test the pH after each time to gain an understanding on how it reacts to the water/nutrient formula. You do not want to drop the pH so low that you need pH up.

It is not recommended to use both pH Down and pH Up in the same solution as this will affect any pre buffered medium. Always take care when using this product, wear gloves and avoid contact with skin/eyes.
