How do I raise or lower the pH of my water?

pH moves faster than you think, so dose small and do it after you have mixed the nutrients. Overshooting and then chasing the number back and forth makes salt build up. GEN200 pH- and CANNA pH+ both state a target range of 5.8–6.5 on the label, which fits most set-ups.

To lower: GEN200 pH- or BioBizz Bio-Down. To raise: BioNova pH+ or CANNA pH+.
