Is it possible?

[jjjimmy]

I want to add a closed loop to my set up but I do not want to completely break my tank down to drill holes in my AGA tank.

So...

Is it possible to tee off of the drains in the overflows (one on each side) for the feed and then run an OM 4-way up the back and over the top of the tank to the four corners? I am more concerned about the drain feeding the CL pump than the return plumbing to the tank.

TIA

Interesting idea, tagging along.

An overflow drain will not work for a CL source as the majority of the line is air.

You can run new lines to/from the pump over the back, be sure to add a "t" at the high point with a cap. This will be used for priming the pump.

Why not use Tunze streams?

Check out Melev's website on how to add a CL without drilling. I did it to mine as a temporary solution so I could hook up my dart. Works great.

I already am with a wavebox also. I am looking for more flow w/o more internal pumps.
