This is unit has a deep-water reservoir, all built into the compact design, and complete with a small pump to move the water down the leaves in a dripper fashion. The force of this flow can be adjusted to provide as good a flow as you require.
This comes with a suction cup on the back which allows for easy installation onto a glass surface - please note this unit can become heavy with the water in, and the suction cup alone will not allow for a high placement, but is better sat on the floor with decoration around. For wooden vivariums, this could be installed on a screw, though care should be taken to ensure the size is correct for both the unit and the wood - this is not supplied. Alternatively you can now purchase the base unit to hold the unit in place and looks amazing!
The leaf detail means the water drips down, creating a perfect area for reptiles to drink from, and the water is then constantly flowing through the unit via the pump in the reservoir. Included in a carbon pad, helping to clean and purify the water.
