Do not clean your fish tank frequently as it can kill the beneficial bacterial colonies. However, if there is visible algae growth, it is time to clean the tank. Make sure you never use soap or any other kind of detergent, as the chemical residue can harm your fish.
Follow the steps given here for a thorough clean-up.
Step 1: Take Out Your Fish
Use a fish net to remove your fish from the tank and transfer them to a large bowl or bucket with some water from the tank.
Step 2: Clean the Glass From Inside
Grab an algae pad and clean the insides of your aquarium thoroughly. Algae pads are readily available in pet stores. For stubborn dirt residues, you can use a razor blade.
Step 3: Clean the Decorative Items
Take out the plants and other decorative items from your aquarium and soak them in warm water. Scrub gently with an algae scraper to get rid of the algae. If the residue is truly stubborn, mix 1 tsp. of bleach in ½ a bucket of water. Soak the plants and decorative items in the bleach solution for 10 minutes. Rinse the aquarium rocks and plants with water until there is no chlorine smell. Don’t forget to use rubber gloves when using bleach.
Step 4: Clean the Gravel
Use a water siphon pump to clean the debris from the gravel. The pressure in the gravel vacuum should be able to suck the debris from the gravel without sucking the gravel itself. The water that gets sucked in along with the gravel debris should be replaced with dechlorinated water. Water that contains chlorine is not safe for your fish, thus, it’s important to use dechlorinated water.
Step 5: Clean the Exteriors
Now, it’s time to clean the exteriors of your glass tank. You can use vinegar or a cleaner that has been labelled aquarium safe. Be sure to rinse the surfaces with a clean, damp cloth.
Step 6: Clean the Filter
Put back the decorative rocks and plants in the aquarium. Clean the filters at least 15 days after cleaning the rest of the tank to maintain good bacterial levels in the aquarium’s ecosystem. Use a filter brush to clear the sludge. Soak the filter assembly in a bleach solution for 5 minutes and then rinse all the parts with clean water thoroughly. Always use rubber gloves when using bleach.
Your fish tank is now a clean and happy place.
