Description

Make water-changes truly hands-free. The Qanvee S3 combines a quick-prime squeeze bulb with a screw-tight rim clamp that locks the siphon to your tank, so you can focus on churning gravel instead of chasing hoses. A telescopic intake tube slides to the perfect depth, while a smooth-bore hose keeps detritus moving steadily toward the bucket.

Models:

S3

  • Telescopic rigid tube: 35 – 49 cm
  • Flexible hose: 152 cm ≈ 5 ft
  • Tubing I.D./O.D.: 9 / 12 mm
  • Rim-Clamp Knob: screws tight to the glass for genuine hands-free siphoning
  • Best for: nano to mid-depth tanks and anyone who wants controlled, splash-free water changes

How it works

  1. Tighten the clamp knob onto the tank rim.
  2. Drop the intake tube, making sure the bucket is lower than the tank.
  3. Squeeze the primer bulb twice—water starts flowing in seconds.
  4. Stir the substrate; debris rises and exits while clear water returns.
