OFFLINE

Using a filter bag and a bucket, we can quickly and easily clean and remove the debris from the bottom of a jellyfish aquarium (in this case, a Cubic Orbit 20). This can be done frequently, as it's pretty simple. You can vacuum the bottom while doing a partial water-change pretty easily, but this can be done in-between water-changes and the water poured back into the tank.
