Atlas Scientific pH Up and Down 250ml (8oz)

Easy use good product does what it says

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.

However this allows for more control and accuracy. And for some reason I seem to of had lower ppm readings with this product than others. Just have to use more.

Not a bad product but should come with a way to test it. I had pool strips and it didn't show any ph going to get another meter and try so may update review after that

As advertised, shipped quick, TY!

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!

Seal was received broken and bottles bent

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!
