first thing: dont take the 1048! its absolutely noch necessary.. a 1046 will be more than enough.
second thing.. why pvc? plug and cool is much more secure and much easier to handle.
and you could need some "winkel" (90°).. and, of course, a set for "entkopplung" for the eheim would be a good idea.. it is just for a much more silent pump.
P.S. dont drink and write a foreign language..
