Discus Buffer™ helps to replicate the ideal Discus environment (low pH & low GH (General Hardness)). Discus Buffer™ will lower pH and keep it lowered. Discus Buffer™ also softens water by precipitating calcium and magnesium. Use Discus Trace™ to restore the proper level of trace elements required by thriving, healthy Discus. DIRECTIONS: Use 1 level teaspoon (7 g) for every 40 L (10 gallons*) daily until intended pH is reached. Thereafter, use once a month or with water changes as required to maintain pH. To raise pH, use Neutral Regulator™. To target a particular pH use in combination with Neutral Regulator™ following the chart below. This chart assumes the use of unbuffered water (RO or DI). If water is already buffered use the chart as a starting guide. Use Prime™ to dechlorinate tap water before doing a water change.
