AQUANEAT Aquarium Vacuum Siphon, Fish Tank Water Changer, Gravel Cleaner, Hand Pump

The Aquaneat Aquarium Vacuum Siphon is a manual gravel cleaner and water changer designed to handle routine tank maintenance without complex setups. It simplifies both draining dirty water and refilling your aquarium, making it a handy tool for everyday fish keepers.

Starting the siphon is straightforward: submerge the 1.5-inch inlet nozzle and hose into the aquarium and squeeze the integrated hand pump bulb a few times to get the water flowing. To keep the flow moving naturally, the water level in your tank must be positioned higher than the discharge end of the 5.25-foot hose.

For safety, the inlet includes a filter screen to prevent livestock from being pulled into the tube. This makes the cleaner suitable for aquariums housing small or delicate species such as bettas, guppies, dwarf cichlids, glofish, and goldfish.

Keep in mind that this cleaner is recommended for tanks that are 5 gallons or larger. Because it relies on gravity once primed, you will need adequate vertical drop between the tank and your collection bucket to maintain steady flow, and the listing does not specify tube materials or valve types.

Verdict: The Aquaneat Siphon is an affordable, practical solution for aquarists managing tanks 5 gallons and up. It provides safe, simple draining and filling while protecting small fish from accidents during water changes.

A great fit if you:

• Keep small fish like bettas, guppies, or dwarf cichlids and need a safe intake filter
• Own an aquarium that is 5 gallons or larger
• Want a simple manual hand pump to start siphons without using your mouth
• Need an all-in-one tool for both draining and refilling water

Consider something else if you:

• Have a small nano tank under 5 gallons
• Cannot position your drainage bucket lower than the aquarium water line

How do you start the water flow?
Place the nozzle and hose into your fish tank and squeeze the pump bulb several times until water flows. Ensure your aquarium water level is higher than the discharge end of the hose.

Will this siphon hurt small fish?
No, it includes a filter screen designed to prevent fish such as bettas, guppies, dwarf cichlids, glofish, and goldfish from being sucked into the tube.

What tank sizes is this cleaner recommended for?
The siphon is recommended for aquariums that are 5 gallons or larger, featuring a 5.25-foot hose and a 1.5-inch diameter water inlet.
