I finaly broke down and set up an Auto top off system on my FOWLER 90g. Its a basic set up with mechanical float switch mounted in the sump,a reservoir and plumbed through the wall directly into my RODI sytem. Its been the best upgrade yet. I am now wanting to have ATO's on 2 other tanks that sit on each side of a large couch and at the opposite end of the house from the 90g. Running a line isn't an option. Looking more towards stand-alone furnitue style ATO system, not just a 5g bucket with a pump in the bottom. Anyone have pics of a neat,clean stand alone style you have built and use?
Thanks,
Jon
