Here's what I am doing to try to fix it. Right now I have cut a piece of acrylic to fit over the top of the 20 gallon frag tank. It should cut down on the evaporation some, as long as it does not melt. I am going to leave it there and see how much there is evaporated from my autotop-off container. Secondly I am going to invest in an ro/di unit. If it is really going to be evaporating even just 10 gallons a week, I think I need to invest, although I would have to say that it won't be too soon. $$
