seeing who is running the mp10s on ther 12g nc.. was looking to get some pics to see how it looks in the tank my concern is that its going to take up to much space in an already small tank.. thank you

Its only 2 inches long on the wet side. Its most likely smaller than whatever pump you have in there now.

really.. NICE! do you have any pics of one in a 12g tank?

I have one in a 14g Biocube. It looks pretty good.
Plus, its smaller and looks a lot better that a koralia nano.

Having some trouble making waves though. Can only seem to make a wave if I turn it up to 75-80% but at that speed, the sand bed starts to loosen.

Well it's not a pic of just the mp10, but you can go to my little unloved thread: http://www.nano-reef.com/forums/index.php?showtopic=202711 and look at post #9 and see basically the proportion of the mp10 to the tank.

(for reference though, it takes up a lot less space than k-nano's and the like)
