It will vary depending on what you're growing and where your particular plant's needs fall on the nutrient/ph charts. For hydroponics/coir it is recommended by manufacturer to range between 5.5 and 6.5. **Q: can you list ingredients with %. Thank you!** A: exact amounts are a trade secret however the MSDS on this states:Phosphoric acid 10 - 30%Ammonium dihydrogenorthophosphate 5 - 10%Citric acid 5 - 10%in comparison the dyna-gro ph down has:Phosphoric Acid H3PO4 33%Nitric Acid HNO3 11.5%That being said there are benefits to some of these ingredients. N-NitrogenP-PhosphorusK-PotassiumPhosphoric acid provides: PAmmonium dihydrogenorthophosphate provides: N and PCitric acid: other than lowering ph, does nothing useful. made from oxygen and hydrogen not in any usable form as far as I can find.Nitric Acid provides: NOverall either product seems to provide similar benefits.Dyna-gro is half the cost. **Q: ingredients? Concentration?** A: It’s not organic if that’s what you mean ingredients. I haven’t used this in a long time. I want to say I’d use like 20ml for 5 gallons. I switched to another branf **Q: Is this safe for aquaponics systems?** A: I would think so. I use it to lower the pH of the water I use to water my plants sometimes, both inside and out. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Product would buy again. *by A***R on July 13, 2026* I have a simple hydroponic tower with a 5 gallon water capacity and this pH down works excellently.
