To start cleaning your fish tank, start by unplugging the heater and filter. You can then scrape the algae off the sides of the tank. If the sides of the tank are made with acrylic instead of glass, it is recommended to use a plastic scraper (instead of metal). Completely replacing the water in the fish tank is a bad idea because it will eliminate the beneficial bacteria that live in the fish tank and restore the nitrogen cycle, which could kill fish.
You don't need to clean the fish tank every day, unless you see the fish behaving strangely (gasping for air or acting slowly). The following steps will explain the best way to restart your aquarium without having to start over completely, as well as how to keep an aquarium clean. How often you'll need to clean your fish tank depends on the size of your aquarium, the number of fish, the types of fish and the filtration system you have. More than just an aquarium cleaning service, Fish Geeks offers a full line of professional aquarium services.
If that's not the case, you'll need to make an emergency water change to ensure that the rest of the fish in your tank aren't affected by what killed the dead fish. Using a window cleaner developed specifically for aquariums is vital to reduce the risk of accidentally adding toxic chemicals found in regular window cleaners to your aquarium. If you have a medium-sized fish tank or a large fish tank, partial weekly water changes can be very helpful in maintaining the fish tank's cleanliness and the health of your fish.
