Whats up reef2reef, So like the titles states, what containers or tanks are you guys using to mix and store water? I got a new R.O unit and from now on mixing my own water, been on the search for a 20 gallon trash can so i can mix the water in, but im so confused on what to get, as ive read on some threads that some trash cans leech things into the water like phosphates. What you guys think ?
