I love my duetto, it's a game changer. I got tired of dumping 1/2-1g a day into my bigger tank.
That is a close second with the JBJ since it includes a cover to protect the sensor. My third option is buying a CoralVue Hydros with their ATO and leak sensor.
I feel like these new methods (electronic) are more prone to failure since my old tanks (ran for 5 years shutdown 8 now) used a tom aqua lift with old school floats. I never had an issue, but my float is just way too big for the evo.
I am curious if anyone runs something like this for redundancy?
I would feel a little better with that and the single point of failure Tunze or JBJ. Just not sure if that would work out in the 3rd chamber.
You mentioned the duetto and a larger tank. So, it sounds like that is not on the 13.5?
