The ability to full integrate my components into the apex is my favorite feature. Also the combination of multiple sensor type. I have never trusted only manual float switches
I already have the neptune apex and leak detection. The system has definitely cut down on the time for maintenance and has prevented some near disasters.
I love that the ATO has a learning feature, so its another layer of protection aside from the manual float and the optical sensors. I love the PMUP as well!
I love that its simple yet effective. Not only is there one back up in case of a failure, but two to increase redundancy. This not only keeps your aquarium safe, but your home too. Thanks for this opportunity!
I like the three preventions. I do not have an auto top off but, I would be worried about it failing and overflowing if there was only a single measure of prevention.
