I'm using the culligan brand water machine, 5gal a time. It's $1.28 to refill 5 gallons so I just do that instead of shelling out for a RO unit. Also my chem department has multiple units....I haven't asked to see if I could use it yet lol.
2.5 gals each for my 2 shrimp tanks, my crays get tap. The tap here is ridiculously hard, the stains are ridiculous.
I'm a 3rd year undergrad at St. Bonas studying chemistry, G.W. medical program.
