Hey all! I'm currently setting up a macroalgae tank and as a college student, an RO/DI system isn't practical. I was wondering if I could use distilled water instead. I know it's not as good as rodi, but maybe the macros would like slightly "dirty" water? There is a water machine at my local grocery store that claims it's RO water that I've been using. I know it's not going to be very clean (I ordered a TDS meter to see how bad it is), but maybe I won't have to dose trace elements if I use it? Feel free to tell me if I'm being an idiot, just figured I would see what everyone's thoughts are
