Looking for cheap & easy auto-topoff

[Jack]

Hey Steve,

Ya, nice auto-top off. Gives me a good idea that I can work off of (in other words, copy ). I have a question though, how did you get that 1/4" line fitting threaded into the jug? Ever thought of dripping kalk? or do you have a reactor?

Also, I was looking at those exact same rubbermaids (the ones with the wheels) everything looks good but the wheels concerned me. I was thinking it might leak there from the stresses caused by wieght of water. What do you think? Would these be good sump tanks? I might just use two of them exactly how you did, one for refugium, one for auto top, and then a large one for a sump. Let me know what you think, thanks.
