My overflow failed today :(

[Son Of Skyline]

Thanks for the responses guys. It's a Lifereef utube overflow and has worked flawlessly for 2 years. I think something plugged the utube for awhile and then moved on, although I don't have any evidence. I have one hermit which is big enough to plug it and it can climb the glass. I do have an ato and it did activate but luckily it shuts down automatically after about 10min so some damage was contained there. A high water float switch in my display may work but it may be an eyesore IMO if I can't hide it. Can a controller like an apex or something control a floor water sensor to cut off my return instead of just sending an audible alarm? Is there a cheaper or easier way?
