Product Components
The GADFISH Aquarium Gravel Vacuum Water Changer system includes the following main components:
- Gravel Tube: A clear tube designed to collect debris from the aquarium substrate.
- Control Valve: A brass valve for regulating water flow and switching between drainage and refilling modes.
- Water Hose: A flexible hose, approximately 30 feet in length, connecting the gravel tube to the control valve and faucet.
- Faucet Adapters: A set of upgraded metal adapters (55/64", 15/16" or 13/16", 3/4" GHT) to ensure compatibility with various faucet types.

Setup Instructions
- Connect Water Hose: Attach one end of the water hose to the gravel tube assembly and the other end to the control valve. Ensure all connections are secure to prevent leaks.
- Select Faucet Adapter: Identify the correct adapter for your faucet. The system includes multiple metal adapters (55/64", 15/16" or 13/16", 3/4" GHT) to fit most standard faucets. If necessary, use the included Teflon thread tape on the faucet threads before attaching the adapter to ensure a watertight seal.
- Attach to Faucet: Screw the selected adapter onto your faucet. Then, connect the control valve to the faucet adapter.

Operating Instructions
1. Drainage and Gravel Cleaning
- Place the gravel tube into your aquarium, ensuring the end is submerged in the water.
- Turn on your faucet to a moderate flow.
- Open the control valve on the water changer (usually indicated by an "ON" position or lever). Water will begin to flow from the aquarium, through the hose, and out of the faucet into your sink or drain.
- Move the gravel tube through the substrate to siphon out debris and waste. The integrated filter device in the gravel tube prevents fish from being sucked in.
- Monitor the water level in your aquarium and the clarity of the water being drained. Stop when the desired amount of water has been removed or the gravel is sufficiently clean.

2. Adding Water (Refilling)
- Once drainage is complete, close the control valve on the water changer (usually indicated by an "OFF" position or lever).
- Ensure the gravel tube is still positioned in the aquarium.
- Adjust the faucet to the desired temperature for refilling your aquarium.
- The system will now reverse flow, drawing water from your faucet and directing it into the aquarium.
- Monitor the water level and turn off the faucet once the aquarium is refilled to the appropriate level.
