i can be home made...anything...that is simple to use..and that has a safty float switch..aka 2 float switches...don't want my tank to overflow...or if someone could make me one...i would be willing to pay..
if ur just looking for a cheaper model go w/ californiareefs.com I have a single float switch thats been going strong for almost a year now. I will upgrade at some point though to something more professional.
