My friend was talking to me about a system. In which you take a gallon of water. Make sure its above the hieght of your tank. Take 2 tubes. Put one in the bottom of the water jug and put the other one in the tub. From the bottom tube place it in the tank and with the upper tube place it in the tank and make sure it stays at the exact water level that you want it. Then when the water goes below it suctions hould bting water in.
Would this work?
Have you heard of this?
Thanks

That sounds like a Nurce style auto top-off.

There are many DIY threads about how to make one. :)
