1) isolate Tank from the sump....
2) insert Sand in sump and i have used external filter, for remove dust.
3 )insert bacteria.
4) after 3 hours ( after the water had become transparent) i have switch on pump for go back water in tank.

First problem....nitrites 0,5.......used vodka and bacteria, after 6 hours nitrites 0,2......

How long have you been dosing vodka? I remember you mentioning nitrate problems in previous posts. If you've been carbon dosing for a while, that should be under control. Do you have any type of filter pads or sponges in your system that could be trapping disolved organics?

I use vodka from many time, The sand that i have insert comes from old DSB.....i think that was more polluted, so it have product NO2.

Do you plan on using a plenum with the DSB or just different grades of sand?

To start, the display tank (150 gallons) is going to be setup as a mixed reef tank with live rock and a 2-3" sand bed that will be cleaned and replaced as necessary. The tank drain will be plumbed through a 75 gallon tank with a 6" DSB that will be stocked with benefitial sand sifting critters (bristle worms, snails, and some hermits for any leftover food that might make it down there). In turn that tank will drain to a 40 gallon long sump. The sump will be configured so that the water draining from the refugium/RDSB will enter a skimmer compartment, then travel through a bubble trap into a properly lit chamber that will house chaeto, through another bubble trap, and then into the return chamber. I am planning on running around 1500 gph through the return system. Primary parameters are going to be controlled through the use of a quality calcium reactor, sea chem prime, and chemi-pure elite. I will most likely be tying in a 30-60 gallon frag tank into this system as well.

I am planning on running the RDSB without lighting, in the hopes that the critters will work harder at cleaning and keeping the sand bed turned over. Do you all see any reason that this may come back to bite me in the you know what, especially later on down the road? What if I decide to turn the DT into primarily SPS dominate later on?

Grant:

I'm not sure if you have seen this thread [Dave's tank]; it's now a BB [bare bottom] tank with a variety of SPS. Here is the link: http://www.atlantareefclub.org/forums/showthread.php?t=88457">http://www.atlantareefclub.org/forums/showthread.php?t=88457</a>

I'm not sure if this thread is helpful to you. It's an amazing tank with a BB; I wouldn't think it being possible.

Yeah, I have been considering running the DT bare bottom, but would still probably run a remote DSB.

The DSB help you to manage in natural mode the reef, imho!
