 Re: Cheatomorpha???
I know! It's confusing and overwhelming at times! 
My thinking was this....DSB's definitely offer denitrification benefits....but....eventually they exhaust and cause some problems. I put is in my fuge so I can shut it off from the rest of the system, tear it out and replace it. I would also at that time, put all NEW salt water in the fuge. Just incase there was a release of hydrogen sulfide, it would not get into the main tank.
Best of both worlds. Up to you! Some folks do the sandbed with the mud on top too! Sorry, didn't mean to confuse....  _________  I Love My Sig By John Hawkins!!!!!!!!!!!!!
