Hi, I am new to the hobby and I am planning to setup a FOWLR system at some point but still in the planning phase.

One thing that came out from some of the research I made was that some people get leaks or flood from either
their sumps or fishtanks do to different reasons (Poweroutage, siphon from main tank, not enough room in sump etc...)

I was wondering if there was a way to build the system to avoid having flood or leaks as much as possible.

For instance, does a pre drilled tank with a sump still could flood ? I tried to do research and could not find
anything to provide tips on what to do to totally avoid floods.

At some point I was even looking at something like the Red Sea Max 250 as everything is in the same tank and therefore would remove the flooding potential, but would not be suited for bigger fishes and is more a reef tank than a FOWLR.

Could you guys direct me on how this could be achieved.

Thanks
