KH difference in 2 tanks
In the past I assumed both of my tanks would have the same KH. But since I went to pressurized C02 I thought I would check both tanks c02 ppm. I found that my 29 gal tank with Flourite had a KH of 6 and my 10 gal tank with plain gravel had a KH of 5. I didn't think Flourite effected the KH. I just changed water in both tanks yesterday.
I just thought I would pass this along for others to read.
