Does what it says it’s supposed to do
Raise the pH it was good. It works good.

Powerful Downer
Great stuff. I cautiously added just a little to my ten gallon reservoir, ph took a good dive. Had to add more tap water to bring it up to 6. I would recommend a ph meter. As water may differ in ph, so would the amount of solution needed per gallon. Add very small amounts, and test. This stuff is hands down solid.

Strong PH Down Dosage
Stronger than other PH Down products I’ve used, make sure to gauge PH after small additions, this product goes a long ways.

Best product on the market
Fox Farm hands down makes the best grow products out there. This stuff is so potent. My tap water comes out around 7-8 ph, and I want 6. I have a 6L hydro system and only need 1/8th of a tsp of this, which actually brings it down to 4 ph. I thought my PH tester was broken so I bought a new one, and it gave the same readings.

Temporarily lowers pH
I can't say that it doesn't work because it does. It will lower the Ph level. The problem I seem to have is that It will not hold it for very long. I can add a couple ml of this stuff to the DWC and it will be back up after a couple of hours. Is that normal? I don't know but it really annoying. Going to grab another pH down product and test it out.
