Helped Cure My Hydroponic PH Blues
The village we live in has well water from a Lake Superior aquifer and the TDS and PH is not great.I was running at around 7.5-7.8 PH in my hydroponic system where I am growing, spinach, swiss chard and a number of lettuces. Optimal PH is 6-7.I have a 10 liter #4 drip system and the instructions said to add 3ML of the solution per litre but also cautioned that a little goes a long way. I halved the recommended mix and added 15ML of PH Down to 10L of water. Within 30 seconds my PH was at a stable 6.5.Super happy, great product, highly recommend!

A little goes a long way!
I’ll start by saying I’m using this on water that’s already been through a 4 stage reverse osmosis system. That being said I’m already pretty close to the desired parameters.I’m making my water in gallon jugs and using a small syringe to add the solution.I needed to lower my PH just one full number and all it took was less than 3 ml of solution to do it. This should last quite a long time if it continues to be this efficient.So far I’m pretty happy with it. The bottles are pretty small but as little as it takes to adjust your levels it doesn’t really matter.

I was skeptical…
After reading the reviews I was skeptical but when it arrived and I treated the water that started with a ph of 9.3 and put a few drops in it dropped to 4.13. It worked great!!! Seals were good when opening looked brand new and worked as it should!

Meh
Works for what I need but seems to take a bit much to change overall ph for larger amounts of water, other brands offer solutions that can change a gallon or multiple gallons with a few drops but this takes a full 2ml for a noticeable difference. Works alright but not the highest quality, lasting long enough for me for the value and came without leaks but will be getting another kind to ph the water for my plants' nutrients since it's more than just a liter of water.
