Use a pH tester to gauge whether your water requires an adjustment. Nulife pH Up Solution will allow you to increase your pH level as required.
Approx 4mls per 100 litres of water will increase the pH level by one unit (ie. from 5 to 6). It is recommended to only use small amounts on your first time (i.e. one drop at a time), test the pH level after each addition of concentrate to gain an understanding on how it reacts to the water/nutrient formula. You do not want to raise the pH so high that you need pH down.
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.
