been running the dual float switch for 4 years of constant use. Best investment I have made in equipment to date.

This. I have one on each tank. One for over 5 years. No problem at all.

I hadn't seen that. I like the configurability and that there's an Apex interface. Hmmm...

OK here's a new question. I have 2 side by side 9 gallon nano's and would like to buy one system to control them both. Any suggestions? Since they only take about a gallon of water a week for both I would hate to buy 2 separate systems. There must be someone else out there with the same setup.
Thanks for any suggestions.

I'm pretty sure only if they share a sump...

Uses a digital air pressure sensor so not float valves or float switches to go bad or look ugly in the display, only the small clear tube.

I have use a spectrapure liquid level controller for many years with out any problems. I dont know why its not more popular. It works great and you never have to worry about keeping a float or eye sensor clean.

autotopoff.com been using their product for 3 years now with literally not 1 problem. They are inexpensive and all of the parts you could ever need are right there. Fast shipping and cleaning of the components is literally a breeze! It even comes with a pvc guard to protect against snails or any other critters getting in there and causing the float switch to stay in the on position.
