|   A shallow sand bed has no nitrate reducing qualities.  All of the reading I have done has led me to believe that it is purely asthetic.  If I understand it correctly, a shallow sand bed can become a nitrate factory.  Maybe I'm out to lunch but that is what I have read. Why would I ditch the filter floss? It is my only means of removing larger particles before they settle.

|   I have 1/2 cm sand bed which I clean. I run filter material also. But even though you clean the sand bed you should have cuc to get detritus and uneaten food before it breaks down |

|   There are a few sand sifting snails that live in the sand as well as a handfull of hermit crabs and a handfull of turbo snails.  I never used to clean the sand bed but recently have been reading that a shallow sand bed should be kept clean so I started cleaning it in hopes it would help.
