ro di ?

[sb62nova]

I bought a ro di form Bulk reef supply. I have well water, so will the rodi remove all the cal. also will i have to dose for that now?

it will remove all impurities, I was never aware that our well water contained calcium in it, if it does, it would never be enough to supplement your tank anyway. Depending on what you keep, most the time your salt mix will contain enough if you are changing your water once or twice a week.
