When you use a hygger water changer to suck away aquarium dirty water, you can move the gravel tube to clean the gravel or install the duck-billed one to clean fish feces.

Step 4: Open the gravel tube valve, then the dirty water will be sucked into the hose and flow away.

Tips to Use the Water Changer

1. If the faucet has a sprayer or filter head, you need to unscrew that and then screw the connector onto the faucet.
2. When you drain the water from the tank, the water flow assembly valve should be open. Please close the vacuum tube valve first. Only after you open the faucet, can you open the vacuum valve.
3. For suction to be provided, the water needs to remain running while draining the tank.
4. The sinks you are using should be level with the tank or lower than it.
5. To turn on or off the orange control valves on the water changer, you just need to rotate the valve by 1/4 turn up or down.

    Works great, but if you need a replacment hose, it’s not 5/8″ OD 1/2″ ID. It’s actually metric 12mm ID 16mm OD. A 5/8×1/2 will slip off through the screw fitting and spray water everywhere since it’s more prone to kinking and isn’t as thick.

      Hi William Moore, the hygger 966 water changer has the 3 length sizes of flexible tubing available ID 12 mm OD 16 mm in the last photo.

    Love this water changer! Completely changed my hobby for the better! NO MORE BUCKETS!!!! The faucet adapter fit my sink perfectly, no adapter needed for me. Love the accessories that come with this as well. I love the switch up by the siphon, that is a GREAT idea! I don’t have to just unload a ton of water using this feature. I can shut it off also if fish accidental swim up in it.

    This water changer works extremely well! I replaced my aqueon unit with this one, and it works perfect! The support for my questions were very informative and pleasant.
