Our 55-gallon tank was cleaned and the 3D background was redone. Our cichlids and Black Skirt Tetras are safe in a separate 20-gallon aquarium, awaiting their return. The goldfish are in the main tank to begin the Nitrogen Cycle, and to test the safety of the water for the other fish. Aside from the high Alkalinity levels. we have taken every precaution to ensure the safety of the fish. Meet Wakko, Yakko, and Dot. More on them later! NOTE: It's called a NITROGEN CYCLE, not a NITRATE Cycle. We know about our mistake.
