General HydroponicspH Down - 8 Oz

Works perfectly.

Always good.

General hydroponics is my go to for ph down. Arrived quick

Works very well. Like another reviewer said, " only takes a small amount." My water source has high alkalinity, so I use a syringe from a "Teeth Whitening Kit" and use about 4-5 drops in a gallon of water to get a Ph neuteral reading....6.5 - 7 according to my Ph strips.

First of all, I really like and use General Hydroponics products. I use General Hydroponics Floraseries. I've tried other products, but always come back to the Floraseries. I use their products for growing cannabis. If it's good enough for NASA to use on the space station....it's certainly good enough for me. The ph down is a decent product. I simply use citric acid crystals. It's half the price and you only use 1/4 the amount. Last forever. Just need about an 1/8th teaspoon compared to 1/2 teaspoon of ph down.

Great for lowering the ph in my yap water

Blah blah works as it should

I’ve used this specific brand for a while now and I’ve noticed it takes about 1ml worth to bring my tap down to 6.5 my tap water comes out around 8.3
