Seachem Acid Regulator 250g (SC-76)
Acid Regulator adjusts water pH to 4.5–5.5, precipitates calcium and magnesium, thereby softening the water and makes the water suitable for all acid-acclimated species (such as neons and other tetras, etc.).
For further freshwater environment enhancement, use Fresh Trace to restore the proper level of trace elements and feed NutriDiet Tropical Flakes for thriving, healthy freshwater community fish.
Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to acid pH.
Directions
Use 1 level teaspoon (5 g) for every 40 L (10 US gallons) daily until intended pH is reached. For precise dosing use the Seachem Digital Spoon Scale. 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. 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.
To target a particular pH use in combination with Neutral Regulator following the chart.

FAQ
Can I use Acid Regulator in a planted aquarium?
A: Yes, it won't harm your plants, however, Acid Regulator is a phosphate based buffer, so you may experience some unwanted algae growth depending on usage. For lowering pH in the planted aquarium, we recommend Acid Buffer. Acid Buffer is a phosphate/carbonate free buffer for lowering and stabilising pH in the acid range of pH 46.8.
What is the difference between Acid Buffer and Acid Regulator?
A: The difference is that Acid Buffer is a straight acid source and Acid Regulator is a phosphate based buffering system. Acid Regulator has a greater ability to maintain a pH as were a straight acid source can have a slight pH drift. When you are trying to avoid any additional phosphates I would go with the Acid Buffer and Alkaline Buffer products but if that is not an issue, then the Acid Regulator will maintain a more constant pH.
Can I use Acid Regulator alone to keep a pH of 6.8 or so, or do I need to use it with Neutral Regulator?
A: You can use Acid Regulator by itself to achieve a pH within the range of 4.5 - 6.8, adding slowly until intended pH is reached. We recommend using Acid Regulator in combination with Neutral Regulator or Alkaline Regulator to maintain a slightly higher pH or to increase pH (if your pH is lowered too quickly, etc).
