Nano Rocks are way too big

[Reeferhead]

How big are the nano rocks supposed to be? The two I got from Marine Depot are probably a 12"x6"x4" and look like the ones for a full size Stream pump but have an adapter ring so that they'll hold a 6045.

The ones I have certainly don't look like the picture posted on MD's site. Also, I though I read on here somewhere that the Nano Rocks were supposed to be built so that you could still utilize the magnet holder. Help me out because I'm confused.

MD charged me the Nano Rock price and the box says Nano Rock on it but these things are huge.

The rocks are only about 6" around. It is part 6025.25. Our box would be a small white box measuring 6 by 6 by 4. It has a label that is about 1" by 2" that reads NanoStream Rock 6025.250 and has a bar code. It only holds the nano stream. The fully size Stream rock is part 6200.250 and measures 10 by 10 by 6 and it only holds the full size streams, the box is brown cardboard. Do you have a picture of what you got?

I don't have a pic right now but the rocks I was sent were in a brown box. I'll have to take another look when I get home but it sounds like they sent me the 6200.25
