Aqueon Siphon Vacuum Gravel Cleaner, Large 16 in
Aqueon makes the Large 16 in size for aquariums of 40 gallons and up.
A gravel vacuum you start with a few quick up-and-down strokes of the tube in the water: the old water runs down the hose to a bucket, and the tube lifts the dirt out of the gravel while the gravel falls back.
Consider: Sized by Aqueon for 40 gallon and bigger tanks. The water goes into a bucket, so a big water change means several trips.
US version, item 100106231. Check what’s in the box before you buy.
Specifications that affect fit
- Made for tanks of
- 40 US gal and up
- Hose length
- 6 ft
Before choosing this model
- Set the bucket lower than the tank: the water only runs downhill.
- Clip the hose to the inside of the bucket so it can’t jump out when the flow starts.
What Aqueon doesn’t publish
- Aqueon publishes the tank sizes and the 6 ft hose, not the tube’s width.

Included items & upkeep
- self-priming intake tube
- 6 ft flexible hose
- hose clip
Plan for the routine work
- Move the tube up and down in the water a few times to start the flow.
- Push the tube into the gravel and lift it: the dirt goes down the hose and the gravel drops back.
- Watch small fish and shrimp near the tube while it runs.
- Add a water conditioner when you put new tap water in, as Aqueon says; its label gives the dose.
