Negative-Pressure Aquarium Fish Viewing Tower
See your aquarium from a new angle
Add an above-the-waterline view to your aquarium with this clear negative-pressure fish chamber. Once filled and installed correctly, the raised chamber connects to the aquarium below, allowing appropriately sized fish to swim into the elevated viewing space.
- Clear PC plastic chamber for observing fish
- Uses atmospheric pressure to hold water above the aquarium’s normal surface
- Approximately 7.48 inches high × 4.72 inches wide × 5.12 inches deep
- Three mounting hooks shown for attachment at an aquarium corner
- Supplier-listed for tank glass less than 0.75 inch thick
- Includes air-removal accessories according to the supplier
The supplier also describes water from the chamber replenishing the aquarium as its water level falls. This is a raised viewing chamber, not a conventional sensor-controlled auto-top-off system, and it still requires regular water-level and maintenance checks.
Check mounting clearance, glass compatibility and fish size before use. Follow the supplied filling and installation instructions, keep the chamber opening submerged and test stability before allowing fish access. This chamber does not replace adequate aquarium space, filtration or routine water changes.
