I have been looking at 125- and 180-gallon MegaFlow tanks from All-Glass, with the built-in overflows. According to their little diagram, the water doesn't just "overflow" over the top of the overflow, but it is allowed into the overflow through three locations in the plastic at varying heights —a slit in the bottom, a slit in the middle, and over the top. I saw mention of flooding with sumps... and it seems to me that using this design, if the power went out, the water would just keep pouring through those slits and totally flood the sump and then your floor, not to mention totally draining the tank. Is there something to prevent his, aside from installing a whole backup battery system?
Aren't there overflows that only take water over the top (as opposed to through slits lower down), so that if the power went out the water would stop draining once the tank level is so low it won't reach the top any more? Are these better?
TIA!
