They not the same skimmer as ASM, the Octo's are built better and their cheaper. Maybe ASMskimmer just read the writing on the wall.

I own the Recirc 200 and couldn't be happier with it. For 71 gallon of water I would go with the 150 or the Recirc 110 if you can swing it.
The recirc are better but for the price they offer the non-recirc in you can buy a large one that would out compete the smaller recirc. The recirc can be used externally out of the box if that matters to you.
Da colts has the 200 and he was quite impressed with it as well.
