Pond Boss Forums GENERAL QUESTIONS Water chemistry Water Testing

WIth an alkalinity of 12 ppm I recommend 4 tons/acre more is even better. You can not over do ag lime applications. At this rate even with a modest flow rate you may be over 20 ppm for 3-5 years. Have you calculated your retention time?
1. Simply measure your outflow water (gals/min)
2. Calculate your volume number of acre/feet or ultimatley gallons (2.7 million gallons/acft)
3. Divide gallons by gals/min and figure your retention time. (1440 mins/day)
This will let you know how effective your fertilization program might be.
Good luck
