My daughter has caught multi-aquarium-itis. Probably from me. She just bought an old tank from someone who had it in their garage for a while. Considering the fish food that came with it excited before she was born, a long while.
Step one: set up and fill with water outside. Failure would likely happen in the first few days and better a wet carport than 55 gallons in the bedroom. LOL
Step two: clean, drain, and move to new location.
Still to come: fill, decorate, inoculate, cycle, and eventually get some fish.
Her #aquarium is going to look great!
