Tunze 3152 ATO

[jmags080307]

My 3152 ATO is twitching every 5 to 10 seconds. Anyone have any ideas why it's doing this? I purchased it new in October 2018 so it's not even a year old.

When they run for a longer than normal amount of time, the little brain in the black box on your power cord gets scared, and shuts off the pump until it is rebooted. It’s a failsafe to help prevent flooding.
You should be back to normal if you just unplug and re plug your unit.

Worked! Thanks.

Worked! Thanks.

Awesome! That should mean it’s working as designed!
That being said, I would be investigative as to why it triggered it, whether it was just a really hot day causing more evaporation than normal, possibly algae or vermetid snails growing on the float valve?
Either way, if it’s been in use for a little bit and this is the first time you’ve experienced this feature of the system, I would want to find out what caused it in order to make sure nothing is amiss.

Hope this helps, happy reefing!

Keep in mind these are delivered preset for a 25 gallon or less tank, pages 16-17 explain setting a longer timer for 25-55, usually if they time out frequently, the tank setting was not set properly for tank size.
