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 ### ⭐⭐⭐⭐⭐ Review *by S***N on April 2, 2024* ### ⭐⭐⭐⭐⭐ Review *by R***R on March 21, 2026* ### ⭐⭐⭐⭐⭐ Review *by S***D on March 3, 2026* ## Frequently Bought Together - General Hydroponics pH Down Liquid Premium Buffering For pH Stability, Quart - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart - VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/13974373-general-hydroponics-hgc722120-liquid-premium-buffering-for-ph-stability-quart](https://www.desertcart.jp/products/13974373-general-hydroponics-hgc722120-liquid-premium-buffering-for-ph-stability-quart) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-05*
