That's what happend to me. I was all, "clean BB tank, here i come!", until I actually saw all that bare bottom. The rocks looked weird without the sand. Someone on canreef said it best.. the ocean isn't BB.. hehe. But this is all just personal preference, like boxers or briefs. There's not right or wrong answer ( I don't think ).

They do the work alright.. just don't get the type of goby that takes in gobs of sand, then hauls it into the water column and spits a trail of it out from one end of the tank to the other

Anyway, with careful powerhead direction you can avoid hitting the sandbed and blasting it. This is another reason why I like the tunze 6105 vs an MP40. The MP40 has such a wide wave that it would surely hit my sand bottom, especially since my tank is only 20" tall. I think the mp40 has an 18" diameter flow or something like that. With being able to direct the flow I can blast a narrowish stream down each side of my 6' tank, have it hit the other end of the tank and flow back through the centre of the tank without touching the sandbed. It actually works out quite well for me. 6800+gph and no sandstorms.

That's the first time I have heard that arguement regarding tunze vs mp40... I've got a mp20 running 100% on Reef crest, 6" above my sand bed (in a 24x24x12 tank), and it doesn't stir up a single grain of sand...

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!

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!

(... 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
