Things You'll Need
- 5-gallon bucket
- Hose
- Small fish net
- Small clamp
Instructions
Place a 5-gallon bucket near the fish tank.
Place the hose inside the center of the fish net. Pull the net tightly around the end of the hose to prevent siphoning fish from the tank.
Insert the hose with the netting end at least 4 inches below the surface water level.
Place the other end of the hose in your mouth. Suck on the hose until it is half-full with aquarium water.
Remove the hose from your mouth and place the tip in the 5-gallon bucket. Siphon water from the fish tank until the bucket is full.
Fold the end of the hose over and secure it with a clamp to stop siphoning. Empty the bucket.
Replace the bucket next to the fish tank. Hold the clamped hose over the bucket. Release the clamp to continue siphoning. Repeat siphoning, emptying the bucket and clamping the hose until you've removed the desired amount of water.
Take the end of the hose out of the fish tank water toward the end of the last bucket to break the siphon. Hold the hose vertically so all the water drains into the bucket.
