water Top off for Nano

[Octupus]

Good day!
any recommendation on the availability of water top off for a nano? i have 14 gallon and travel quite a bit. I only have corals and shrimps and wondering if there is a way to put a water top off mechanism. I would think i would have to use Fresh water as this is what i top now. Would appreciate any recommendation or if there is anyone selling such a tool. thanks!

This is the controller I use http://www.bulkreefsupply.com/Auto-...ntroller-w/2-Float-Switches/product_info.html to auto-top off our sump. Just get an aqualifter for it and let it do it's thing when the sensors say the water is low.

As far as top-off systems go it's pretty cheap I think.
