I was just speculating as I have never owned an MP40. Just saw pics one of that was put too close to the sandbed once. The Mp40 is more powerful than the 20 isn't it? I wonder how close you could put that puppy to the sandbed. It would be really nice to have both and try them both out. I don't know too many people who have/had both though.. They are so expensive, you typically either have one or the other and you love them because they are so damn expensive! :-)

Obviously a mp40 would be too much in a tank the size of my cube, but at only 6" off the sand with the mp20 (2000gph), I think its a good indication of what an mp40 would be like even 10-12 inches high... If it was an issue, you'd probably see alot more people complaining, rather than praising! :lol:

Well, luckily both Tunzes and Vortechs are cheap like borscht so it's easy to just buy both and try each, and just keep the one you like better, and just toss the other one in the recycling can! :lol:

(... Well, that's the way it would be if *I* were king of the universe..)

Yeah I don't see the 6100s up in the rear corners as being a problem with the sand at all since everyone has those right there. It's the 6101 I have near the bottom rear that I might need to re-position.

Tank's half full. My flow test won't be for a bit yet! This wait is WORSE than the previous 1.5 yrs

Water is maybe a few mm from spilling into my overflow box. Damn this is brutal haha. Have all 3 Tunze on and yeah the sand certainly gets blasted bad in a few spots. Have to wait and see if that bacterial coating on the grains thing helps me any.

I have both Vortech MP40w's & Tunze's in my reef.
I place rubble in the high flow areas where the sand gets blown away, works well and in my opinion looks quite natural.

Full pics?? :mrgreen: Seeing as your "webcam" hasn't changed for days... :wink:

Im also running both (mp40 and two tunze 6055s)...the combo has turned the tank into a 50/50 split of bare bottom up front and sand at the back....I like both powerheads for what each has to offer....vortech for wide flow pattern and shear power....tunzes for their point-ability

Very interesting and entertaining read. Congratulations on your tank Brett, it looks really great.

The dust settles. Lastlight for the win! Be a while till the salt settles though!

I bought this over a year ago. It's a relief to say that so far this thing appears to foam like a BEAST.
