My tank water is not alkaline, but the tap water is.
How is this possible/being done?
Normal metabolic processes in the tank reduce the pH of the water. I think
the alkalinit of the tap water is at least in part produced by CO2, so it's
easily removed by the plants.
The water pH usually hovers around 6.8-7.0, while the tap water is around
9.
