Seachem Acid Regulator 500g

Acid Regulator™ adjusts pH to the acidic range (4.5 – 5.5) and softens water by precipitating calcium and magnesium. Acid Regulator™ supports the establishment of the optimal environment for all acid acclimated species (e.g. neons and other tetras, etc.). For further freshwater environment enhancement, use Fresh Trace™ to restore the proper level of trace elements required by thriving, healthy freshwater community fish.

Acid Regulator is a phosphate based buffer, so it's not suitable for planted aquariums. For lowering pH in the planted aquarium, we recommend using Acid Buffer.

Sizes: 50g, 250g, 500g, 1kg, 4kg

Use 1 level teaspoon (7g) for every 40L 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.
