Updated: Almost got a disaster this morning.

I Got up this morning and checked the tanks. My RSM 130 had no water movement because i forgot to turn off the switch last night after feeding my coral. Fortunately, everything is still alive because of my temporary tunze skimmer was running inside the tank.

Then noticed the water in my main tank was hitting the top screen. Checked the overflow and saw one is jammed :-( Thus my ATO filled all fresh water from top off bucket. Fortunately, it is only 5 gallon so it ran out of water to fill otherwise i would have a wet floor and wife would be mad.

Now I installed a float switch in my overflow to detect if it jammed again, it will shut off the return pump.

Again, 2 lessons learned from this

1) Never have a big reservoir top off water
2) Must have float switch to detect when an overflow occur.
