When using chemical fertilizers, it is advisable to adjust the pH after adding the fertilizers. Stimulators should be added after the pH has been adjusted. B.A.C. pH down and pH up are also used to remove bicarbonate from hard water. To prepare the solution, add pH down until it reaches pH 5.2 and allow the acid to react with the bicarbonate. The water will then drop to pH 3. With pH up, raise the pH to the appropriate level according to the substrate you are using and whether the fertilizer is organic or mineral. Refer to the pH charts.
