The Johnson would challenge an Eheim 1060, which is bigger than the 1250 (which is bigger than the 1048).

The spec flow rates, for comparison (including amperage@12 volt):
-7.1 gpm @ 3.3 feet (2.2 amps)
-5.3 gpm @ 6.6 feet (2.0 amps)
-3.0 gpm @ 9.8 feet (1.6 amps)

I don't get it.... The Johnson is rated for 70 watts...
2.0A * 12v = 24 watts? @ 318 GPH = 3 times better then the MCP600? at a bit more then double the wattage?

So one Johnson pump should outperform 2 MCP600? and use only little more power. right?

If this is surely the case, I will stop waiting for rev2 of the MCP (who will have a 0.5 meters better head) and get me 2 mag driven Johnsons from surplus! (one as backup, as they seem to fail a lot)
