The KH is consumed to an extent with all filters. The bacteria use the
carbonates to help with the digestion/conversion of ammonia to nitrite, giving off a Hydrogen ion, and then in the conversion of nitrite to nitrate, 2 Hydrogen ions are given off. These hydrogen ions are acid and they use the carbonates to neutralize the acid and convert the hydrogen ions with CO3 to CO2 and water. The pressurized filters, bead filters are generally associated with heavier fish loads than the garden pond with smaller filters, and therefore more food to be converted, more acid, more demand for carbonates/bicarbonates to prevent a pH crash. -- RichToyBox http://www.geocities.com/richtoybox/index.html "~ jan JJsPond.us" wrote in message ...
