It contains three electrolytes to help maintain osmotic balance. When used as directed, it will safely lower pH levels in nutrient solutions and never harm plants.

Review: A little goes a long way! Dose in small amounts. - Very potent so literally your best bet is to use a 1ml syringe and add 1ml at a time. I treated 5 gallons of water with just 1ml bringing the ph down from 8.5 to 5.2. With that said the size is great for the value. The speed at which it takes effect is less than 3mins. It’s easy to use if you go slowly. Definitely measure out the dose, otherwise the ph will bottom out which can be saved with ph up but you’ll end up making a chemistry project instead of feed water.
Review: Good stuff - Works pretty great although when I received it in the mail the ph up way 1/4 short due to it leaking

### ⭐ Ph has not dropped
*by K***E on January 13, 2026*

I should have the read the reviews a bit more closely. I have used almost half of the bottle and my pH for the hydroponic tower garden is still at 7.5. It looks like I would have to use an entire bottle and even then I don’t know if it would work. I don’t like leaving bad reviews, but this one just seemed like a waste of money.
