The DATO

Since our rather large saltwater tank loses a tremendous amount of water each day due to evaporation, the more water evaporating increases the salinity of the remaining water in the system, so after reviewing a bunch of different designs I created my own Automatic Top Off system to replace any evaporated water automatically. No more lugging 5 gallon buckets of water up from the basement each day!!

Since I’ve never seen a system designed like mine I’ve adopted the name DATO (Dakar’s Auto Top Off) for my design 😛

Here’s a simple drawing of how it works, for more info look at the DATO thread on Captive Reefing.

Feel free to adopt my design, or adapt it to fit your own needs.
