Ideal for adjusting large volumes of nutrient solution.   \u003cbr\u003eKey selling points:  \u003cbr\u003e\u003c\/p\u003e\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 \u003cbr\u003eTechnical Specifications:   \u003cbr\u003e\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: 250 ml \u003c\/li\u003e\n\u003c\/ul\u003e \u003cbr\u003eFAQs:  \u003cbr\u003eQ: How should I use Essentials LAB 30% pH- to adjust the pH level of my nutrient solution? \u003cbr\u003eA: 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. \u003cbr\u003eQ: The pH level of my solution is already low. What should I do? \u003cbr\u003eA: If the pH is within the recommended range, you should do nothing. But if the pH is too low, then you should use Essentials LAB pH+ to adjust it to a higher level, within the recommended range. \u003cbr\u003e \u003cbr\u003ePurchase this with…  \u003cbr\u003e09-410-022 - Essentials pH Meter - With Memory Function \u003cbr\u003e09-420-070 - Essentials LAB pH+ 250ml \u003cbr\u003e10-485-035 - 10ml Plastic Long Pipette - 1ml increments \u003cbr\u003e","brand":"ESSENTIALS","offers":[{"title":"Default Title","offer_id":53420894683479,"sku":"09-420-005","price":3.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2558\/9335\/files\/09-420-005_1.png?v=1777303332","url":"https:\/\/hydrohub.org.uk\/products\/essentials-lab-30-ph-250ml","provider":"Hydro Hub","version":"1.0","type":"link"}
