Intense Nutrients PH Down Ultra 250ml

Remember when 1 bottle of pH down used to last more than a day?...

...those days are back

High-Strength, Phosphorus-Free, Regulatory Compliant pH Control

pH Down Ultra from Intense Nutrients is a powerful and reliable solution for reducing pH in nutrient tanks — without the drawbacks of traditional phosphoric acid.

Formulated with 70% methylsulphonic acid, this advanced pH adjuster matches the effectiveness of older 81% phosphoric acid products but without spiking phosphorus levels. That means cleaner feeding, improved nutrient stability, and no compliance worries for retailers.
