So my ATO is beeping at me, im out of RO/Di water in my can because its showing 8 TDS. My question is, will it kill my corals or be detrimental to them if I run off enough water to top off till my filters get to me??? And im broke, so cant go to LFS, and i live in the middle of nowhere so probably couldnt go snagg a couple 5's from a fellow reefer. So, idk...
