The KH/Alkalinity at 75ppm is roughly 4 dKH. This has no effect whatsoever on fish or plants, but it does act as a pH buffer to maintain the pH at the level in the tap water. But not being high, the pH may well lower in the aquarium due to the organic processes. Which would certainly be better, with soft water fish.
Byron, just goes to show you. The anecdotal information for this area has always been that we have hard water. I was going by that and decided to get the actual numbers after seeing so many suggestions on the site to do so. My primary concern is with the PH. First, it seems to greatly limit the variety of species for which I could provide a healthy environment. Second, it seems to run contrary to the hardness of the water. Any thoughts ?
