The Oase biOrb Cleaner Pump works like a siphon, but has a squeezy hand pump to get the water flowing. Simply hold one end of the cleaner pump in the biOrb 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.
