I use Rubbermaid garbage cans. I have a dolly under them with wheels so I can have it in another room with my RO and then I can wheel it to any of my tanks. It works great and its cheap. I also use a cheap walmart air pump to aerate it and a heater to get it to tank temp. Depending on your water you may need to treat for chlorine and other unwanted crap. Maybe try some Prime by seachem. There are many others to use. Im sure sombody will chime in with others
