Hey everyone, been wanting to add some CRS to my cherry shrimp tank for a while now. The shrimp tank is an established, planted 10G and the RCS are thriving in it. My levels in the tank have all tested well, my only concern being with the hardness. I usually just use treated tap water for all my water change outs so naturally using edmonton city water my levels are pretty high in all my tanks. Alot of what I've read up on about the CRS is they can be quite finicky and prefer a softer water (4-6gH). Just wondering if anyone else out there has had much experience with them and whether or not the hardness is something to actually be concerned about with them.
