The Hygger HG919-800 is a submersible water changer pump built for one job: making water changes quick.
215 GPH (800 L/HR), quiet in operation, with run-dry protection so it won't burn itself out if the level drops below the intake. Drop it in, run the hose to a bucket or a drain, and you're done — no siphon to start, no arm held over the tank, no bucket balanced on a chair.
Useful on anything from a nano up, and particularly good if you're running several tanks and water change day is the chore that keeps getting put off.
Come see it at either of our San Diego stores.
