What is the amount per gallon mixing ratio?

I use up to 3-4ml per gallon sometimes, depending on my nutrients, water and stage of plant growth. 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.

can you list ingredients with %. Thank you!

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.

ingredients? Concentration?

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

Is this safe for aquaponics systems?

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.
