I've used a 10g glass tank as my ATO for years on my 120. I fill it once every 5 days or so...3 float switches and a Minijet 404 pump..good to go![]()
You can do 3 - one for high water level as fail safe, one for low water level to activate the pump to fill and one in the reservoir so the pump doesn't run dry.
