Overflow help

[Baldy]

I have a lifereef hob overflow atm. its good quality, and has never failed, but it's intrusive inside the tank and out. And a pain when fish realize they can hide behind it when I'm trying to catch them. Next tank I own is going to have an external (hopefully coast to coast) overflow with a beananimal setup

I would go two. Depending on flow. One for drain one for emergency. Last thing you want is a plugged drain and a full sump still pumping into tank
