You don't want to put an elbow right at the inlet to the pump, it will constrict flow and cause cavitation and overheat the pump. RE requires a 4.5 - 7.5" long inlet pipe at least 1.5" diameter.

RE sells them on its German website, but they are very pricey.

Not sure since its not a male end. It's not intended to fit into anything. If you want to increase the diameter of the inlet you can get a 2-1.5 inch reducer coupling
Aces are you currently using the pump?

Which one would fit over 1" PVC? I don'y mind paying for it but want to make sure I get the correct part. Would this work? http://royalexclusiv.net/Accessories/silicon-anti-vibration-sets/silicon-anti-vibration-internal-Mini-Red-Dragon-pump-2-5m-5m::465.html

I'll have to check my pump again, I thought the inlet was 1.5" not 1.25". Are you sure he's talking about the inlet side? I'm also not clear why he is linking you to a 32-25 mm reducer bushing and two hoses, one at 32 mm the other at 30mm. If it is 1.5" you should get the 38 mm tube: http://royalexclusiv.net/Spare-Part...silicon-tubes-38x5mm-per-1-2-meter::1299.html
Tonight I'll check the pump for the size and let you know.
Another way to do it is to use flex pvc. Not as soft as silcone, but alot easier and cheaper to deal with. These pumps are so quiet, I would bet that if you used flex pvc to connect it to the sump (put a true union ball valve in between to make it easier to service without draining the sump) and set the pump on a neoprene isolation pad you won't hear a thing.

It's not available yet and won't be until later first quarter 2015 as I far as I am aware. For your size system, that may be overkill. If your head estimate is correct at 5' including friction loss, the RD3 80 watt will provide you over 1500GPH at 5' head which will be plenty (5x turn over) for a return on a 300 gallon display. This assuming you aren't running a bunch of reactors. Do use that head loss calculator on the link I provided in that other thread as that will take into account PVC size, elbows, unions, gate valves etc. This way you get an accurate head pressure number including friction loss as all those things factor into head pressure over and above how high the return lines are.

Having sold Speedy pumps exclusively for a long time, what kind of reliability have you seen with them - complaints, warranty, etc.
I have to decide between a Speedy or drilling my new sump for a Reelo pump, and I'd love to justify the cost of a Speedy - but I need some help. I have had a horrible experience with DC pumps from other manufacturers in the last couple years =\
