A simple set up is best. Filter, dechlorinated water, few rocks on a slope and some water plants. I put liquid calcium drops in mine when I did water changes. I only put in one dropper full, not the normal recommendation. You don't have to though. They get some calcium from the foods you provide. Do a partial water change every week and especially at the 2, 3, and 4th week because you'll have a bacterial bloom. After that, the stink and cloudiness will slow down and you can do biweekly water changes. The "good" bacteria will then live in your filter and rocks, and they will aide in breaking down fecal matter and left over food. Oh yeah, they can also nibble zucchini.
