I own a commercial hydroponic greenhouse and this is the ONLY pH down brand that I use and I’ve used it for several years. It does exactly what it’s suppose to do. If you have used this before, please read the instructions on the bottle - otherwise you will need to buy some General Hydroponics pH Up.
