If for Top off water due to evaporation- RODI water

Do you use tap?

Only for cleaning and rinsing. Tap water NOT worth it. With so many sales on RODI units- worth the now small investment.
For starters, the amount of Alk in tap water can potentially double this number easily and affect CA and PH not to mention content of heavy metals, chloramine, polluants. flouride and other elements not contained in sea water. tap water also offers no ph buffering and note many areas have copper in their taop water which you do not want in your system. Next will be phosphates in water which will cause further issues.
As you can see - Risk is the issue
