Water Evaporation

[LittleGecko]

Is building a sump underneath the paludarium the only way to stop evaporation? I had serious evaporation issues in my crested gecko viv so I scrapped the water feature all together. I'm currently working on a 20 gallon for reed frogs and i really want to include a water feature but im pretty sure the bottom is tempered glass, and having a sump for a 20 gallon seems like a waste anyway. Are there any other alternatives to stop this?

Thanks, Corey

Sumps don't stop evaporation, they redirect the placement of water level drop.

If the sides of the glass are not tempered, you could use an elbow instead of a stand pipe. But really, the whole process is a bit intense to go about anyway.
You could try putting a float in the water feature, which could activate an external water source to pump water into your tank every time the water level drops beyond a certain point.

Other than that, cool the tank. If your animals need a specific temperature that is generally high, then there is nothing else I could think of to keep the water level. The ONLY other idea could be having the temperature of the tank warm and the water constantly flowing cold using a thermoelectric cooler (one designed for this purpose is pretty expensive... at that point it would just make more sense to by a larger tank without tempered glass and make a sump for it), but chances are either the tank will get cold or the water will get warm anyway. Hope this helps.
