If I could give less stars I would! The PH Down is super weak.
Reviewed in the United States on October 6, 2025 by James Jackson
I’m reading this at three out of five stars not because it didn’t work, but because it required a lot more solution to balance my tapwater compared to other brands. I almost had to use twice as much of this pH up compared to the general hydroponics, but can’t attest to the pH down as I never needed to use it. The indicator solution worked well, the solution actually worked and adjusted my water, I just burned through the bottle way faster than I should have. Going forward I’ll stick with general hydroponics but this would work in a pinch!
