Goliath pH adjustment formula is specifically designed for use with Hydroponic, soil & soil less media as effective pH control.Nitric acid is a strong and highly effective pH adjuster for hydroponics because it can quickly and efficiently lower the pH of nutrient solutions. In hydroponics, it is important to maintain the proper pH of the nutrient solution because plants absorb nutrients most effectively at a specific pH range. If the pH of the nutrient solution is too high or too low, it can affect the plants' ability to uptake essential nutrients, leading to poor growth and development. Nitric acid is able to quickly and effectively bring the pH of the nutrient solution into the optimal range, ensuring that your plants have the right conditions for healthy growth. Additionally, nitric acid is highly concentrated, so a little goes a long way, making it a cost-effective choice for adjusting the pH of your hydroponic system.
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.

First time using ph down. Supriced how little you use to correct the ph in the system.
