Goliath pH adjustment formula is specifically designed for use with Hydroponic, soil & soil less media as effective pH control.

Directions Of Use:

Take it slow to ensure you are not overdosing, we recommend dosing in increments of 1 - 2ml at a time until you reach your desired pH Level.

If you’re using the pH down in a Hydroponic nutrient reservoir then make sure to add 1:4 of water to dilute the adjuster prior to adding to the Nutrient tank.

Best practice is to test your pH levels before and after to determine the exact pH of the solution.

Make sure you are not winging it, only use the correct safety equipment and testing instruments.


Nitrogen (N)......................1%

Phosphorus (p205) 5%
