HOB filter as a overflow box?

[cichlaguapote]

Your best bet is to figure out a way to use PVC to get water into the HOB with PVC or some other siphon.

That's where your S pvc comes in right? to pull water in the box and then use a seperate pump in your sump to pump it back up?

Kind of, I thought of a different way, which would be easy, and I think it will work. (i've never tried this, if it's moronic and wont work please chime in)


Hang the filter on the tank, and divide the HOB into 2 sections. Drill one section to go to the sump, then keep the other section water tight with the inverted U tube submersed. Start the pump to prime it, the shut the pump off. After that it should act just like an overflow. Here's a crap illustration to try to explain what I'm talking about

(left is the back of the hob/overflow, and the other is the side of the tank it might go on)

Silicone?

I have some HOBs laying around, I'll give it a shot when I get some time.

Silicone wont always stick to plastic very well. It would probably work, but I'd use something else to be safe.
