I think the Eheims will only be for the RC skimmers. Yes, it would be too large for the small skimmers like the 80/100/135 that use SP2 or SP3 pumps. It is pretty much equivalent to an SP4. On the other end, the SP5 outperforms the Eheim, so I dont see it going on a RC250. The RC500, 750 use 2 and 3 SP4 pumps, so they may get them.

Will there be Eheims for smaller ER units like the CS100?
