I second the idea of sand being a trap for detritus. Just get rid of a little bit every time you do a water change.
I 've gone BB and my ORP went up 60 points in one week. That tells me that sand bed takes a lot of oxygen. Also with BB it is so easy to syphone all out when doing water change so staff has no chance to decay.

Also try testing your carbon for nitrates. Aparently some types of carbon can contain nitrate and release it into the water.

Okay we'll thanks everybody for the input. I am going to start taking the sand bed out slowly. And then i am going to see how that works and if not i think i will try the denitrator and see if that works. Hopefully that will work and that will be the end of it. If not i dunno. My confusa is pretty mush gone but the acroporas still look okay so i guess we will see what happens. If not i will just give up on sps and go with softies

Thanks again
Craig

I wil keep it updated anyways
