Do Acro RTN events occur less in BB tanks?

[scyphozoa]

Has anyone had experiences with both a tank w/ sandbed and one w/ barebottom such that they could say that Acro RTN seemed to occur less with one?

(I realize that there are so many factors that contribute to RTN & that any answer to this is merely speculation but I'm curious anyways.) Although I don't think it to be the intial cause of RTN, I've always suspected that my sandbed (& the sediment that occasionally gets stirred up into the water column) helps speed up the coral's demise by introducing scavenging micro-flora and secondary infection.

......On a side note, wouldn't it be nice if all those nasty war-fare chemicals that corals emitt into the water were visible to the naked eye (also ich for that matter). It seems like there is an invisible war going on all the time and all we get to see is the RTN ending.

My guess is BB may actually increase your likelyhood of an RTN event. The reason I say this is because as you get lower in nutrients, while the coral looks healthier (more colorful) they are also less forgiving. A SPS in a high nutrient tank, while they tend to look brown, seem to be much less likely to RTN on you. That is my guess.....That being said, whats the point of running SPS if you dont get good color? That also being said, you can certainly get good color w/out going BB. My colors are pretty nice and I have sand....

I have BB and my colors look good as well.
