Ro make up water

[A Reef Scene]

I have a water tap under one the tanks I take care of and I think that is has copper pipes. If I run the water through a sediment filter, a carbon filter, then a kold steril unit and then the ro unit will I still have copper in the water? The ro is a Kent hi-s unit.

Your water should be like 99.9% pure .

I was just over worried about the copper.
