Does anyone have a Bullet-1 under their tank?

[Delphinus]

Trying to figure out how to set up the plumbing for this. The sump is a 20g tank, drilled for inline pump for the return. I have plenty of space leftover in the stand, footprint-wise that is, to fit the bullet-1 skimmer, however ....

Since the outflow has to drain "straight out or downward" this means the output of the skimmer needs to be higher than the walls of the sump? In which case there's no way I can fit this skimmer under my tank since I don't have a 4' tall stand ...

It looks like my options are maybe to shoehorn the skimmer in behind the sump (so in between my sump and my back wall), which I haven't looked into as a possibility yet, I don't know if this means I need to move my tank forward (which I don't really want to do, I have left myself 4" of clearance back there between the wall and the stand, anything larger will give the appearance of being in the middle of the room ... ??? )

Or perhaps drill the sump (I don't have a glass bit large enough, the instructions for the bullet say the drain must be at least 1-1/4" and you shouldn't use a smaller pipe size ?) So I'd have to take the sump somewhere to get it drilled, but I guess that's not that big of a deal...

I don't really have enough room IN the sump for the skimmer, it would fit, but I mean it would be absolutely shoehorned into there, and possibly impossible to remove for cleaning and maintenance and etc.

So anyways if anyone has this type of skimmer I would appreciate any advice (pictures help a lot too if possible, hint hint )


....

I'm almost wondering if I should just put this skimmer on the other tank (where the sump is hidden in a back room so no issues of real-estate) and just use my RSB on this tank instead. Intended inhabitants are (from my soon-to-be-decommissioned 50g) a yellow tang, two percs, a monstrous ritteri anemone, and a few various LPS and softies.. so not really too huge a bioload (heck I haven't even been skimming my 50g in the last month at all) ... Whereas the other reef is heavier on the SPS, and has a 6line, lawnmower, sailfin tang, banggai cardinal.

Anyways like I said any advice is appreciated as I am just totally stumped on how to proceed here. Thanks in advance!!
