HOB Overflow

[camps23]

Hi all,
Im still on the fence with all the things I have been reading about these HOB overflows. I have found a few with great reviews..(ehopps,life reef..etc) My number 1 concern is obviously flooding the tank. If I had a tom pump will that eliminate any chance of flooding if the hydro goes out and the inlet loses suction ? What is the best setup to give me the least chance of flooding ? How many of you are running them ? any floods or close calls ?
My tank is located in my newly carpeted basement and flooding isnt an option.
Thanks

I would go with the lifereef overflow. I've got the CPR one that uses the Tom's pump, I don't like that it doesn't work with out the pump. If for whatever reason that pump fails, then I'm screwed.

I heard its a balancing act, if you are able to keep the water level in the aquarium low enough that if you lose suction/ tom pump fails your aquarium can support the amount of water from your sump. A big balancing act

That's why I like the lifereef one better, it doesn't rely on pumps and its designed to not lose suction.
