Okay, got the BK Mini 180 today... OMG. First thing I thought to myself is I should have gone for the 160... This thing is a beast!! The riser tube is twice the diameter of my old skimmer riser. Second thought was I didn't realize the Red Dragon mini pumps were as big as they are, considering it's rated to draw only 28 watts (BK Mini 160 is only 16 watts!?!). Then a little bit of panic started setting in wondering if it would fit in my sump. I took rough measurements but still wasn't quite sure. I was going to wait til tomorrow to put the BK Mini 180 in but had to see if it would fit.. Sooo, I yanked my old skimmer out and maneuvered the BK over my sump. It JUST fit into a position where I could slide it down into my sump. Powered her up and....OMG, wow. Took me about 2 mins to adjust wedge pipe and instant thick head of foam. Super quiet as I've read as well. Im mesmerized by the bubble production and efficiency of this modified Askoll. I also noticed the air inlet on top of the silencer sounds like it's sucking air like a vacuum cleaner hose!! Serious Air. Again, wow.
I did notice the needlewheel on mine is black and I've seen posts where Klaus shows a pic of a white needlewheel being CNCed. I wonder if there are different versions or something. Ah well, loving it anyway.
