Many of us have things like 44 gallon brute trash cans that we age water in and treat with nothing more than a heater and water agitation (air pump or power head, your choice).
You should seriously consider checking out the sponsors here for quality discus. Petco from my limited experience with them can be a real crap shoot. Do a little reading on diet too, your discus are eating a lot of fish candy (bloodworms).
