Mix thoroughly and measure with a calibrated pH meter to attain the desired pH reading. Ideal for adjusting large volumes of nutrient solution.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConcentrated acid solution \u003c\/li\u003e\n\u003cli\u003eCan adjust the pH of large volumes of nutrient solution \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e30% phosphoric acid \u003c\/li\u003e\n\u003cli\u003eThis product falls below the concentration threshold for Regulated Substances under The Control of Poisons and Explosives Precursors Regulations 2023.   \u003c\/li\u003e\n\u003cli\u003epH: \u0026lt;1.0 \u003c\/li\u003e\n\u003cli\u003eVolume: 1 L \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eFAQs:  \u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How should I use Essentials LAB 30% pH- to adjust the pH level of my nutrient solution? \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e First, carefully check the pH of your nutrient solution. If the pH reading is too high, then the solution is not sufficiently acidic. Add a small, measured amount of Essentials LAB 30% pH- to your nutrient reservoir and mix thoroughly. Check the pH level again and note how much it has changed. You now know how much a certain dosage of Essentials LAB 30% pH- has lowered the pH in your reservoir, and from this you can judge how much more, if any, you need to add to achieve the desired pH level. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e The pH level of my solution is already low.
