pH is 7.6
KH is 5
I don't see anything about the hardness of the water???? That would be GH.
Tiger, I can *ONLY* suggest this *IF* you can find someone who keeps Crystals in hard water to begin with. Otherwise, if you get Crystals raised in typical parameters and move them to your water, then they might live but there's a good chance that they wont thrive or breed.
Finding someone who has Crystals in hard water with higher pH can be difficult, too. I know that there's at least one person who has done it, but I don't know them personally. They acclimated an entire colony, over *years*, from Caridina parameters to "tap water" parameters. Now, there may be an issue that his Crystals wont do well in the average Crystal parameters when he sells them to other people.
