Hard well water out the tap.
My well water out of the tap is 7.5 pH and high KH/GH. Apparently suitable for a cichlid tank, but not so much for the densely planted, community tank I'm wanting to establish. From what I've read CO2 should reduce the pH some, but would it affect alkalinity. What about peat moss in the filter? Most fish/plants will adapt (stable) hard water condiftions? How true is this? Maybe doing too much research lately and these numbers arent as bad as they seem. Have been reading so many posts lately bringing me in different directions. I have seen posts of tanks where people dont even test water perameters at all, and they look OK and healthy.
