I kinda agree, if you want more flow just get a dual overflow.
I have a CPR continuous overflow with dual inputs on my 125g. I've heard a few people say that same thing, that they are designed for failure, BUT I have never once had any issues with mine. I lose power all the time too and it just goes back to its job when the juice goes back on.
I'm only guessing now, but I think the dual overflows is valid in a large tank just because of the sheer size, probably easier to get more water into the sump. Just a guess though as I am not drilled on my big tank. lol
@tkeracer619- Whats the actual issue with the cpr, I've only heard they are bad from a few places and they never elaborated on why. I'm curious to see if there is a flaw in my setup.
