Gravel Vacuum Siphon – Large

The large gravel vacuum is built for aquarists managing high-volume systems where speed and thoroughness matter. Its wide-diameter intake tube moves significantly more water per pass than smaller models, making it possible to clean a large substrate bed in a single water change session.

The 150cm hose gives ample reach across long tanks without repositioning a bucket, reducing spillage risk. The robust tube withstands the stronger flow generated in deeper tanks, and the wide mouth captures large waste particles that a smaller vacuum would miss.

For tanks housing messy species such as large cichlids, goldfish, or carnivorous fish, a heavy-duty vacuum is indispensable for keeping nitrate levels manageable between filter cleans. Regular deep-substrate cleaning also prevents the formation of hydrogen sulphide pockets that can be lethal to inhabitants.
