@Zoidburg / @Blue Ridge Reef I am currently using Fluval Stratum in the tank. My source water has about the same GH and using the API test kit I cannot visually detect a difference between my source PH and tank PH.The biggest concern I see is using tap water on a buffering substrate.... shrimp do best with stability. It sounds like your pH may fluctuate with each water change that you do.
How do tank parameters compare to source water?
Should I be switching to R/O water?
And if I should make the switch, how can I slowly introduce R/O?
