Another offering that runs dual sensors is the IceCap ATO, but unfortunately, both are optical, although I see no warnings of LEDs lighting associated with it. I run one on my IM Nuvo 20 (in the rear compartment of course), and it performs well, and is a lot less expensive than the Tunze.

I too have run into issues with the Tunze Nano (3 failed over the last couple of years, including 2 within the last couple of months, which is why I tried the IceCap model). I am still using four of the Tunze Nanos (out of current necessity), but will probably retire them in the near future if the IceCap ATO continues to do well.

I have not come across the same percentage of issues with the larger Tunze model, and it enjoys better reviews overall.

7 reef tanks, 5 freshwater tanks, 2 terrariums, 2 dogs, 3 boys, and 1 very understanding wife!

Current Tank Info: Marine: Pair of 40B's, 45W, 50g cube, ADA 45F at home...IM Nuvo 20 and 10 at office!
