How long does Amazonia buffer the pH?
I'm thinking about buying used amazonia that is already cycled, but I don't know how long it will last with tap water. It has been used by the person for 6 months with RO, and I don't know how long it will last with my tap. Do you guys recommend buying used? How long did your amazonia last with RO and tap? I'll be keeping CRS in this tank, so the pH just needs to be 6.6-6.8
