I use a continous non-recirculatory drip system on 75% of my tanks (2gph). I use well water that is relatively soft. The water goes through a temperature regulator that automatically mixes the water to a pre-determined temperature (84F).
My problem so far has been tanks that I can not drill (temperated glass). I'm not quite sure what to do for those (any suggestions??). I guess I could use over-flow boxes that hang on the front?
