i have been buying rodi from an lfs $1.00/gal. i decided to test water after my salt mix but before adding to tank. all # ok but nitrite was .25(1st shade of purple on api test scale) added prime then later amquel still not 0. tested the rodi w/o salt mix also .25. i tested water in 2 diff tanks and poland spring distilled all at 0 nitrite. also i did tds test on rodi and read 185. tap was 220 and distilled 0. tdi tester appears accurate. is it possible/likely that lfs rodi is junk? is adding water to tanks with .25 nitrite dangerous? i believe i have been topping off my tank evap w/this stuff and never noticed an issue.
