Keep your fish healthy and your fish tank clean with these simple steps.
You Will Need
* A large plastic cup
* A large bowl
* A scooping net
* A sink
* An algae scrubber
* Clean gravel (optional)
Use a large plastic cup to remove water from the tank to a large bowl. Scoop fish from the dirty tank and put them in the bowl.
Turn off the filter on your fish tank. Remove half of the dirty water using a cup, and dump it into a sink.
Change about one quarter of the water in the tank every two weeks to keep the algae levels low.
Clean the inside of the tank with an algae scrubber. Rinse and scrub until the glass is clean.
Scoop out the rest of the water until you get to the gravel at the bottom of the tank.
Replace the gravel only if absolutely necessary. The fish need a stable environment, so some remaining bacteria is good for them.
Refill the tank with clean water and restart the filter. Let the filter run for about an hour.
Scoop your fish from the bowl to the tank, and let them enjoy their newly cleaned home.
