Actually distilled is not best. RO
is best. Distilled is sometimes made using copper tubing so you need to check that out but as I said RO
is best and then RO
water. I used distilled water for top off water for several years before going to RO
. I do agree that mineral or spring water would probably have excessive nutrients in it causing algea.
