The biOrb Cleaner Pump works like a siphon but has a hand pump to get
the water flowing and is easy to use. Simply hold the nozzle end
of the Cleaner Pump in the biOrb aquarium and direct it towards the
base. The other end has a blue hand pump which you hold over a bucket.
Squeeze the hand pump quickly a few times and water will start to flow
out of the biOrb into the bucket. Move the nozzle around the ceramic
media to take out waste and debris with the water. Includes an extension for taller biOrb aquariums.
