If you want quality product, the only way to go for the money is Advance Nutrients. I use several of their products, and no others even come close to their nutrients. Ty so much, from a very happy customer.

Best absolute bang for your buck. Last me 10 times as long as the 1 gallon general hydro pics that costs 18 dollars. So the comparison is none existent.

My favorite thing about this is how potent it is. I use an eye dropper to add 4ml to a 7 gallon bucket and my PH is perfect. Bottle lasts forever!

exactly what we needed, our city water is 8.2 P/H and we needed it to be between 5.8 and 6.2. Works very well !!

Very strong. You will only need a small amount to significantly drop pH. The best pH down product I have used.

Compared to the previous Brandi was using this one, I have to be careful to only use a tiny bit.
