Ok so evaporation in my tanks is probably one of my biggest pet peeves in the hobby. I cant stand it. I can keep the situation under control in my smaller tanks without any major hassle with just keeping jugs of RO water ready when needed. The problem begins when I get to my 50 gallon and I can imagine the problem would only get more annoying with larger tanks. Is there a DIY project for quick and easy refills? I have heard of certain consumer gadgets that will do it but I dred asking for what price....if anyone can help that would be awesome. Thanks!
