So my Tunze 3155 failed on me earlier this week. The optical eye sensor failed to stop the fill. Luckily the second sensor kicked in and prevented a mess. I’ve tried every which way to clean the sensor but no luck. I think the unit is over 5 years old.

I tried contacting Tunze about buying a replacement sensor but no response.

At this point, I’m contemplating getting a new Tunze but at $200 for my little 10 gallon nano, it seems overkill.

What is everyone else using on their nano tanks? I was thinking icecap ATO as an alternative.

I’m really looking for one that has dual sensors as it saved me earlier this week.

Any help\recommendations appreciated.

I made my item for around 60 bucks and has been working flawlessly for months now. Found the instructions on nano-reef forum

I have had 2 of these first one was temporary had sensor not refill once or twice but got rid of it fast. 2nd one the newer improved one is on my 25g fir over a year now and its always stopping. Beeping. Need to be reset. Need to cover back are with sponge as light from my hydra affects the sensor i noticed. Needs to be cleaned often. I cannot rely on this to leave more than few days. My tunze i had on my reefer 250 for 3 years didn’t skip a beat.

I had one a few years back and had the same problem. I thought maybe they improved since then. Mine use to beep all hours of the night and the sensor constantly needed cleaning. Maybe it’s hit of miss cause some people have no issues with them.

Thanks everyone for the suggestions.

Someone from Tunze got back to me. They will replace my sensor for $30. No charge for labor or calibration. I’ll be shipping my unit to Texas and will have it back in a couple of days.

Can’t beat that for customer service for a unit that’s over 5 years old.

I have a 20 gallon nano and smart micro ato hasn’t failed me once it’s been about a year! I have many equipment in my nano reef and my favorite is the smart micro ato!!!!!!!
