How Vitalink pH Down 250 Mls 81% Phosphoric Acid works:

Vitalink pH Down is a concentrated phosphoric acid that can be used to reduce the pH of almost any liquid that it is added to. When growing plants in hydroponics or aeroponics, it is necessary to keep the pH of your nutrient solution within a certain range. Different plant species have different requirements but in general most plants like a pH range of 5.5 – 6.5. pH Down is added sparingly to nutrient solution to help keep the acidity within this range.

Using Vitalink pH Down 250 Mls 81% Phosphoric Acid

To grow plants successfully, particularly in hydroponics, it is necessary to monitor and adjust the pH of your nutrient solution on a regular basis. In general, plants grown in hydroponics like a pH of approximately between 5.5 and 6.5 (plant species dependent) with a little bit of variation within this range. This is because plants can only absorb certain nutrients at a pH close to 5.5 and others at a pH closer to 6.5. If your nutrient solution strays out of this optimum range for too long, your plants will not be able to absorb all the nutrients that they need and will become deficient, leading to slowed growth and eventually sickness. To avoid pH problems, and the plant problems that it can cause, it is wise to check and adjust the pH of your nutrient solution very regularly (every day if possible).

To use, take a small sample of your nutrient solution and measure the pH with a digital tester or liquid pH test kit. If the pH of your nutrient solution needs adjusting then draw off about half a litre of nutrient solution in a jug and add a small amount (depending on the size of your reservoir) of pH Down to it using a pipette. Mix very well. Add the contents of the jug back to reservoir in small stages, mixing the reservoir well and re-testing the pH in-between each addition until the desired pH is reached. Always discard any unused mixture carefully.

Warning: If pH Up and pH Down come into contact with each other they react violently and even small quantities can be explosive. Always make sure that the two liquids NEVER come into contact with each other as this can cause a violent or explosive reaction. Ideally use separate syringes, beakers or pipettes for the 2 liquids, or make sure that they are washed out thoroughly after using one before using them for the other. Be very careful when handling pH Up and Down as they are both corrosive and will cause irritation to skin and burns on clothing. Keep out of the reach of children and take appropriate care and precautions when using. Always replace the cap on the bottle and wash out syringes, beakers and pipettes after using them with either of these substances. In particular, they will perish the rubber plunger in syringes if not washed out. If pH Up makes contact with eyes, wash with copious amounts of water and seek medical advice immediately. If it is accidentally ingested, seek medical advice. For more info on handling aggressive liquids, call our team on 01782 749955.
