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 H***S on March 26, 2026* Great value for the money ### ⭐⭐⭐⭐⭐ Review *by P***T on February 17, 2026* Worked amazing for all my plants! ### ⭐⭐⭐⭐⭐ Review *by A***E on April 16, 2026* Always the best! ## Frequently Bought Together - General Hydroponics pH Down Liquid Premium Buffering For Stability, 1-Gallon - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend Of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Gallon - General Hydroponics FloraBloom 0-5-4, Use With FloraMicro & FloraGro For A Tailor-Made Nutrient Mix, Provides Nutrients For Reproductive Growth, Ideal For Hydroponics, 1-Gallon --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/731948590-gh-ph-down-paper-down-3-78l](https://www.desertcart.kg/products/731948590-gh-ph-down-paper-down-3-78l) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-17*
