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.
