I usually have a small freshwater aquarium going at any given time. Today, however, I found a twenty-gallon aquarium at a yard sale. I asked how much it was, and was astounded to find that it was $10 and included a giant bucket of filters, air systems, saltwater chemicals, food, carbon, etc... I'm guessing about $250+ dollars worth of stuff.
On topic, I have heard "horror stories" about the difficulty and expense of running a saltwater aquarium. Considering I already have the supplies, should I go saltwater?
