So since I picked up my Hanna meters I've been checking stuff much more often and with better precision. Well started seeing phosphate increase. Checked her and there. Running phosban. Decided to check RODI storange tank. Out of filters reading is 1 ppm. Water in tank was 60ppm!! The drain for the tank is a little off the bottom so it never completely empties. Well in that water were a few viewable particles. Prob bugs that crawled in to air hole at top. Well I drained it vacuumed out the bottom and wiped it down with paper towels. I shall retest tds tomm
