Seachem Discus Buffer 250g
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 for thriving, healthy Discus.
Neutral Regulator® and Discus Buffer® can be used in combination to achieve a desired pH when performing water changes or adding top off water. The ratio chart below is designed for RO water where there is generally no buffering capacity.
Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to acid pH.
Use 1 level teaspoon (5 g) for every 40-80 L (10-20 US gallons) daily until intended pH is reached. Thereafter, use once a month or with water changes as required to maintain pH.For precise dosing use the Seachem Digital Spoon Scale. To raise pH, use Neutral Regulator®. To target a particular pH use in combination with Neutral Regulator® following the chart. 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.
