Best ATO unti

DFWreefjunky · Nov 27, 2014

I like the JBJ for the two float switches (one in tank, other in sump to turn off pump if top off tank is low) ive also never heard bad reviews on the tunze nano. (going on IM30) just wondering what everyone else prefers through experience. thanks

I have the Hydor unit. Only one I have had and once you dial your pump in (adjusted for flow time), it works flawlessly.

Puratek Auto Level Controller. I've used several different ones, and this one is hands down the best on the market IMO.

I have JBJ on the 150g, but went DYI on the 20g... I like the DIY one way better as I was able to source a better solid-state relay than sold in any retail unit...

PIC of the unit, I removed the batter and added a 12v power supply.
