LF : Lifereef overflow box

[gobytron]

depends on if you set it up right.
Honestly, you wont have any issues if you set it up right.

I would never run an overflow with just one utube or just one drain unless I was very sure I had blocked access to any inverts...like snails or crabs.

I diy'd my current overflow based on lifereef design to add a couple tweaks just for peace of mind.

You can blame me if you like, but the whole point Im trying to make here is that if it does fail (which they can) its because you didnt set it up right.
