pH Down is a biological buffered solution, not a simple acid. It is a precise formula containing a balanced mixture of acids and biological buffers that stabilise the pH by regulating the calcium level.

This product is made up of nitric and phosphoric acid, so that the pH can be regulated and a stable nutrient solution can be achieved, without modifying the NK levels at all, while at the same time it can clean the excess lime in the container (only with hard water).

Application

Mix the product with water, check the pH levels and continue adjusting until the desired level is reached.

Be careful when handling this product as it is a strong acid.
