Reduvit pH ReducerOther

hw Wiegandt

Reduvit pH Reducer

hw reduvit pH Reducer from HW Wiegandt reliably lowers the pH value in freshwater and marine aquariums without adversely affecting the sensitive ion balance of the water. As in nature, the pH is lowered by purely mineral means through the release of acids and the use of basic substances, bringing basic minerals into solution for a balanced, stable adjustment; under normal conditions re-dosing is only needed during water changes. Dosing: add a maximum of 4.5 mL per 50 US gallons, wait until thoroughly mixed, check pH, and repeat until the desired level is reached.
