Okay you guys and gal.
Here's a "what if" question and possible alternative.
This is a long stretch for sure - but I will continue on anyway even though there's a slim chance of this working.
I have little fear of trying new things - even at the risk of looking foolish.
I am not 100% familiar with the RemoraPro, and especially it's spray induction system, and don't have dimensions either, so if the following sounds like a ridiculous approach - just let it be that, and please disregard.
What if you took the Mag3 and mounted it at near the water level in the tank, so as it's discharge port was pointing down and it's inlet suction port was pointing out horizontally along the rear length of the tank. Inlet port under water naturally, as well as the discharge port. If you were to then come off the normal place you would install the pump on the Remora, with an elbow with flex tubing or piping, and ran a small length of this tubing or piping up to the Mag3 discharge port, would it even function properly, or just start sucking air.
My thoughts are more of a DIY modification - which would include using a length of pvc pipe ( 1/2" or 3/4" diameter ) and running this along the back side of the tank to some length, with holes drilled every inch or so, that would allow for some surface water removal, and may not stick so far down in view in the tank.
This would eliminate the need for the big bulky prefilter/surface skimmer furnished with your unit Beth.
When I look at my tank - I don't "see" the very top inch or two in the back of the tank, unless I am kneeling down at "tank" level for viewing.
The canopy would hide this abominable contraption from the top view of your tank.
The pump would still be partially submerged in the tank water for cooling, and may draw some surface water through the pvc pipe surface skimming gizmo as well. It would probably look like a "rigged" set up I'm almost sure, and possibly not even work. I can see some major tinkering with it to get it to the right depth, and even if it did work, water top offs would be critical from that point on.
My fear is that this arrangement may suck air if not positioned deep enough, the pump may be noisy, and that if some air does enter the pump housing - it will make a lot of noise and cause problems. Also I have reservations about how this arrangement would affect the performance of the skimmer itself.
I don't know.
As I said - sort of a long stretch idea that may very well not even be worth the time it took to type it here. It may look ugly as sin as well.
