Thanks tank slave 
Also I meant low PH in regards the CC dissolving. I'm not sure whether this really matters anyway.
I have nothing to loose by trying the slow under gravel filter method (CPW). I might just set up a slow trickle through the sand bed then into the skimmer to aerate out any hydrogen sulfide. If the output is to putrid I might have to set it up like doc.
Anyway it will give me something to experiment with. Having a remote sand bed will limit the amount of detritus that can build up in it so I plan to use it mainly for denitrification rather than waste removal. The main tank has a shallow 2mm calcium carbonate substrate.

Dennis I don't think that the ph would be near that low to dissolve cc.
The ccd in the ocean (area were ph is low and all Calcareous oozes are dissolved) is somewere near 4000-5000 meters deep! If possable I would like to know the ph of the water below the sand bed. So this is why I pay all that money and go to school to learn how calcium reactors work!
thanks Nate D

...but he doesn't need to spend time vacuuming, replenishing, or 're-seeding' his DSB either.
I didn't mean to imply that ldrhawke had been banned... It looks like he removed all of his profile info and gallery and just quietly went away.

I will begin my CPW tank in a week at most, Ill be posting in the newbie forum logging the setup

Its been almost a year. I did have a semi reef tank but tore that down to make way for what i really wanted.

with this CPW sysytem a few pints is drained out every 8 hours continously. The system works great, But a "normal" DSB without a phlemun would give yopu the same results if one did small continuous water changes. a few pints every 8 hours adds up to one to two gallons a day. 60 gallons a month. any tank under going 40 to 60 gallons a month water change will have pristine parameters. You do have the advantage of removing your most nutrient desne water form the systme but a suagr size DSB would have the same effect keeping most waste and detrius on the surface for easy removal.

I drained 5 gallons today. The water had a very strong rotten egg smell and was tinted yellow. I tested the water for NO3 and Phosphates. The NO3 was undetectable and the PO4 was around .10. The Tank water has a NO3 reading of 5 ppm and PO4 undetectable. I guess that means the sand bed is processing all the NO3 in the bed.
