Roommate tried to help.... FML

Sounds like the OP has a siphon type overflow and is mistaking that with a Herbie. Or a drilled tank with an overflow box and no emergency drain.

$hitty luck but you are not alone.

I am sure numerous reefers have had a snail or 2 teach them how to mop.

If you only have one drain then you can't use a valve to restrict the flow safely.

Flash, what type of drain setup do you have? Regular, Herbie ... ?
I have done a couple designs on my overflow box and I am going to end up with a plexi cover instead of eggcrate or mesh or etc.
I was going to go with this



But have since decided to make an acrylic cover. It won't be suspended this time; it will sit on top. It'll have tabs on the inside to keep it from sliding around.
The only things that will make it into the overflow will have to get through the teeth.
