@saltyfilmfolks i have made a simple ato that i will try later. Its an empty kalkwasser container that i drilled a hole in, put some airline tubing in, and siliconed. I plan on setting the jug on my tanks rim, and against the wall, it should stay put there easily. Ill clip the airline tubing exactly at my desired waterline, and it should only flow as the water evaporates, right?
