Microbe-Lift's new product, KH Bio-Active Booster, solves the problem of low alkalinity, which can lead to pH "crash." KH Bio-Active Booster is a great product for maintaining proper alkalinity.
When pond carbonate levels fall below the necessary level, nitrification will stop and will fail to start again. With the loss of KH (carbonate alkalinity) pH levels will vary and pH will be difficult to control as KH stabilizes pond pH.
The natural biological ammonia removal process in ponds referred to as nitrification and:
Maintain 50-100 ppm KH at all times to assure nitrification.
A full flat level scoop (enclosed) will raise the KH by approximately:
80/ppm in 30 gallons (113 L)
50/ppm in 50 gallons (189 L)
25/ppm in 100 gallons (378 L)
Alkalinity, often referred to as "carbonate hardness," or German carbonate hardness, is the measure of carbonate and bicarbonate concentrations in your aquarium water. Alkalinity is a measure of the ability of a solution to neutralize acid without changing the pH. It both controls and maintains water pH. Carbonate hardness is measured in degrees (dKH), parts per million of calcium carbonate (ppm CaCo3), or milligrams per liter (mg/L).
Alkalinity is not the same as pH because water does not have to be strongly basic (high pH) to have high alkalinity. Alkalinity is related to the amount of dissolved calcium, magnesium, and other compounds in the water and as such, alkalinity tends to be higher in "harder" water. Alkalinity is naturally decreased over time through bacterial action which produces acidic compounds that combine with and reduce the alkalinity components.
