Emptying a fish tank is an essential part of fishkeeping. It allows you to clean the tank and remove any waste or debris that has accumulated. Emptying a fish tank can also be necessary if you are moving or if you need to medicate your fish.
There are a few different ways to empty a fish tank. The most common method is to use a siphon. A siphon is a tube that is used to transfer water from one container to another. To use a siphon, simply place one end of the tube in the fish tank and the other end in a bucket or sink. The water will then start to flow from the fish tank to the bucket or sink.
