Frequently asked questions
What makes Intense Nutrients pH Down Ultra different from other pH Down products?
pH Down Ultra is an NPK-neutral acid formula, so unlike traditional acids it won't spike phosphorus or nitrogen levels. It is also described as outperforming citric acid with longer-lasting stabilisation.
What is the active ingredient in pH Down Ultra?
It contains methanesulfonic acid, which gives rapid, stable pH adjustment without adding phosphorus or nitrogen to your nutrient solution.
How do I use Intense Nutrients pH Down Ultra?
Add small amounts to your reservoir, mix, and repeat until you reach the desired pH.
What sizes does pH Down Ultra come in?
It is available in 250ml, 1 litre and 5 litre sizes, so you can pick a bottle to match the size of your setup and how often you adjust pH.
