Limescale preventative for salt sensitive fish?
I just learned about this interesting device to prevent limescale in a garden setting, https://plantsurge.com I wonder if this could be helpful for those of us who use a water softener and could be helpful for fish that are sensitive to salts (e.g., cories). Would be cheaper than an R/O unit (or maybe help make the R/O filters last longer?).
