      Mix one part vinegar in the spray bottle with two parts water. One cup of vinegar and 2 cups of water should be sufficient. Spray all of the walls of the aquarium, focusing on the main calcium deposits. Allow the mixture to sit for 2 to 3 minutes. Use your sponge (or rag) to wipe down all surfaces in the aquarium.

      Check to see if any calcium deposits remain. Some deposits will be harder to remove than others. If there are stubborn spots, try a higher concentration of vinegar on the spot. Allow this higher concentration to sit for 2 to 3 minutes, then wipe down.

      Wash all aquarium decorations (bridges, statues, fake plants) in a solution of vinegar and water. Thoroughly rinse decorations with water. Also, scrub out aquarium with water repeatedly. The safest method of ensuring the water is clean is by testing its pH level while you wash it. If you have nothing to test pH with, wash thoroughly and repeatedly.
