  • Strong and effective Ph control
Size: 1 gal Style: pH Down
Works well for controlling PH. It doesn’t take too much to change it for medium sized 5 gallon containers either

  • Concentrated. Works well
Size: 1 quart Style: pH Up
I use this all season, starting out with adjusting 1 gallon of liquid feet and water. Very effective. As the season moves ahead, I use this weekly if not twice a week a adjust 5 gallons at a time. Concentrated, easy to use. Go slow, mix thoroughly, and take readings often as to not go above your desired PH target. ... show more

  • Lowers pH
Size: 1 quart Style: pH Down
The pH of my water was too high, this easily lowered it with just a few highly concentrated drops. No more brown leaves or deficiencies due to pH being off. Does what it advertises and very happy with the results. No leaks in shipping.
