Hard:Alkaline::Soft:Acid ??? (was Amazon sword?)
my tank is very soft (based on city water info), and alkaline (pH~8
according to my LFS. That's odd. Soft water is usually acid, hard water is usually alkaline. Our local water supply has the following numbers from the city's webpage): gH = 82ppm = 4.6 degrees kH = 52ppm = 2.9 degrees pH = 9.7 -- Victor M. Martinez http://www.che.utexas.edu/~martiv |

yup. that's pretty close to our numbers as well. about 50ppm average
(low=20, high~100), and pH is like 9.3 average.. the tank is 8, so either the fish/plants/driftwood is altering the water, or just going from our tub to the tank changes the pH.. don't know which (since I don't have the capability to check pH yet) linda "Victor M.

Your tap water will change pH after it degasses. Also, normal metabolic processes in the tank tend to lower the pH. My tank is usually around 7.8 or so. -- Victor M.
