Sand bed

There are two basic types of bacteria in the nitrogen cycle, nitrosomas and nitrobacter. There are many good reads on the denitrification process, I think Reefkeeping magazine online has several by authors like Randy Holmes Farley.
 
Here's a picture of my 4" DSB at about 9 years old. I woke up one morning to find a crack running straight down the middle of the tank so I had to take it down unfortunately. I used tap water on this tank too. No refugium, no ATS, no GFO, no GAC either. Just regular water changes and an efficient skimmer.

Yikes! That must have been scary
 
The reason sand stars starve is they dont really eat waste. More macro fauna. So after a bit there is nothing left. Plus the fauna is more helpful for waste. Sand stars are not really clean up crew. I suggest a cucumber. Much better:-)
I have been considering a sandsifter for management of the substrate but a number of publication s state that they are likely to starve after a time; what depth of substrate would be recommended?

Figured as much re suitability; one of the LFS advises it to help turnover sand bed but yes all I've read and your statement seems to contradict the suitability (if makes sense). Yes I thk will stick to the cucumber.
Thanks again
