Thanks everyone. The flood was a headache. It actually happened a second time! Figured out that the float switch for my ATO was stuck in the down position. I was told to clean it but it was worth it to me to spend $10 and buy a new one. Definitely cheaper than messing up the house and losing my livestock. I'm hoping to somehow connect multiple float switches to my Apex system for redundancy. If the first one fails the second one can cut it off? Just a thought for now as I'm not very tech savvy.
Is it too late to tear out all of that foam/rock walls? That's a nice tank, stand and home. I'd get rid of that overflow and install an external overflow. Then, put in a nice minimalistic aquascape to leave room for fish to swim and corals to grow. Please don't kill the messenger.![]()
