## Description

pH DOWN by Microbe Life Hydroponics is formulated with deionized and UV sterilized water and combine two pH adjusters for buffered effectiveness. 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

### ⭐ Great product,but very very poorly handled.
*by T***Y on April 9, 2025*

This review is not a reflection of the product itself. Microblife products all work amazing.The product itself works wonderfully. It's got a great buffer in it to hold the ph steady. The issue here is not with the product, but in how the product is stored,handled ,shipped, and delivered. The product came open with the ph fluid all over the inside of the box and all over the inside of the broken bag that it came in. Could be a bit dangerous for pets if that was left out to leak. If this product is not properly stored, it's not gonna work properly. Unfortunately, Amazon does have this issue quite frequently in dealing with this specific brand of product. Microblife. Ive had to return a couple different items in the past for this reason ,returning a mess like this is so tedious...... This is in no way a reflection on microblife. Their products are amazing.
