modifying Euroreef to recirculate

[TheReefGeek]

What you need to do is cut a hole in the body of the skimmer where the intake of the pump will be, and install a bulkhead and connect the pump to your new hole.

Now the pump is drawing its water from inside the skimmer, and returning the bubbles into the skimmer.

Now you need to feed the skimmer with a water source, a powerhead or the drain line from your display will work. Cut a hole to do this as well.

I have only seen it done on ASM's which have to be run in-sump so leaking doesn't matter, but you will have to make sure all your connections and bulkheads don't leak.
