How to Clean a Quarantine Aquarium

Quarantine fish tanks are commonly used to house both newly acquired fish and as well as those who have fallen ill and need to be removed from an existing, established tank. This type of segregation is ideal for sick fish because medication can be safely administered and water changes can be performed as needed. Quarantine tanks also make ideal starter homes for new fish from a pet or aquarium store so they can be observed and treated for any symptoms of infectious disease. After the fish have been moved out of the quarantine tank, it is imperative to thoroughly clean and disinfect the tank to prevent the spread of bacteria or disease to other fish.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Siphon or hose
• Sponges
• Paper towels
• Bleach (optional)
• Bucket

1. Keep all of your quarantine fish tank components and supplies separate from your regular fish tank items to avoid cross contamination and the potential spread of waterborne diseases and pathogens. By using separate filters, heaters, nets, bubblers and decorative elements, you will avoid contamination problems between tanks. Have a separate set of cleaning supplies, such as sponges, readily available to use with your quarantine tank.

2. Relocate fish into an established tank. Don't put the net you used in the quarantine tank into the established tank. Remove the quarantine tank's filter, heater and accessories for cleaning.

3. Remove and discard the filter cartridge, along with the bubbler's rubber tubing. Rinse the tank's filter and heater with warm water and wipe them dry with a paper towel.

4. Drain the tank's water using a hose or siphon. Once the tank is completely empty, scrub it down with water and a sponge. Dry the tank with paper towels. If there has been a disease outbreak within the quarantine tank, consider cleaning it with a mild bleach solution (no more than 2 percent of bleach mixed mixed with water). Thoroughly rinse the tank to remove all traces of bleach. If the weather is warm, set the tank outside to dry in the sun after wiping it down.

5. Ensure that the fish tank, heater and filter are totally dry. Even the smallest amount of water or moisture can result in mildew once the tank has been stored. When not in use, store your quarantine tank in a cool, dry place such as a closet or garage.
