Essential for Nitrification
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:
*TREATS AMOUNTS FOR WHOLE CONTAINER:
25 ppm→5,335 gal
50 ppm→2,667 gal
80 ppm→1,600 gal
25 ppm→21,340 gal
50 ppm→10,668 gal
80 ppm→6,400 gal
25 ppm→133,375 gal
50 ppm→66,675 gal
80 ppm→16,000 gal
To raise KH in 4,000 gal pond, wanting to keep the KH level above 80 ppm:
To raise by 25 ppm→ add 40 scoops
To raise by 50 ppm→ add 80 scoops
To raise by 80 ppm (in pond that has crashed)→ add 133 scoops!
[Ideal KH level in pond is 100-300 ppm/mg/L, with the higher the better, especially in heavily stocked ponds and lined ponds.]
