Good info and I agree completely... I had that thought in the back of my head as well, if it would be enough pressure to operate the skimmer properly. I thought if it came with something like a Mag12 and he was using something equivalent to a Mag24 that is may be enough pressure to operate, but after I read it comes with a Mag18 as the stock pump I started to question if the pressure from the overflow would work. I think if the skimmer was a recirculating skimmer, ie, separate small pump to recirculate the water in the skimmer, it would probably work fine, but as the only input into the skimmer being from the overflow it is questionable that there would be enough pressure to operate properly.. this is without any type of T, I knew a T wouldn't work after seeing the stock pump they normally come with.
