Yea, the tank that overflowed is an older display with only 1 corner overflow.

The Main display has 2. I have 2 floor drains RIGHT there, but the lousy concrete finishers made them the highest point in the basement.... dumba$$es. I am going to be breaking out the concrete by the fishroom to add a 3rd drain, where all the water likes to pool (yep this isn't my first flood

But its difficult cause there is in-floor heating lines. Do you know where to get those flood sensors/alarms from? That would really come in handy.
Oh, yea and livestock is alll good.
