Hello, all. I just joined the site in hopes of getting some advice on setting up our old 520g aquarium. It's just been sitting in our basement for years and I wanted to do something with it. My plan was to do a lightly to moderately planted tank (sword plants, anubias, maybe some java ferns) with a white substrate/gravel and some driftwood (and maybe some rocks). I would like to stock it with a fairly large school of cardinal tetras and maybe six discus.
My questions to this are:
How expensive is it usually to heat 520 gallons to an appropriate temperature for the above fish?
I read somewhere that discus require weekly water changes of at least 50%. If I keep the tank understocked (and I intend to as it would be much easier to maintain at this size), do I really have to do that much?
Note: I don't plan to put the discus in until I've had the tank running for at least a year.
