Causes of decreasing kH???
Can anyone tell me what actually causes kH to decrease?
June 16th my kH was 10.0 June 21st my kH was 6.0 That's a rather large decrease in 5 days in my opinion? Maybe it's not? Test kits have been verified as good by JL. So, what are the causes of decreasing kH?

- Adding too much Calcium supplement
- Excess CO2 in the air - Critters using Ca for growth - Excess nutrients - Overdosing alkalinity RELATIVE to calcium If you haven't already read this article and then read it again and once more for good measure. I suspect your problem is "Zone 3". http://www.advancedaquarist.com/2002...stry#section-1
