interesting observation

A couple of years ago (there's an old thread out there) I observed my Xenia growth pick up specifically when Monti cap growth slowed to a crawl.
Last weekend we noticed cap growth was once again rampant (y'know- big white growth edge).
This morning some of my Xenia is crashing.
There's definitely some kind of DOC threshold relationship here somewhere...... and once again I've crossed it, this time in the opposite direction (less DOC's once again).
 
The bigger skimmer has a lot to do with DOC reduction. So does yanking the old sandbed and doing regular (rather large) water changes.
 
I remember that discussion. Xenia became entirely extinct in my tank soon after going "low nutrient".

Another observation--echinophyllia won't grow in my tank either--while SPS growth is rampant.

I'll need to monitor Echinophyllia growth. Of course, everything will change after the move next week.
I'll probably have a new outburst of Xenia growth.
