Re: [APD] Ammonium Experiement

[Dennis Dietz <dennisdietz at verizon_net>]

You noticed that also huh?  I was wondering if it were BBA or something 
else.  It may even be intentional (or at least left on purpose) to 
better resemble a type of coral.  IIRC, there is something called a gorg 
that looks like that, though often they are brightly colored.  

We talked a bit about that tank on APC a bit also.  My impression was 
that the amount of N added by NH4 was fairly low compared to the EI 
method but the plants used are more likely to do well in low nutrient 
environments.  The lighting is fairly low aswell.  It looks to me like 
the plant mass is actually fairly low and that the bulk of the layout is 
taken up by rocks so the amount of nutrients need is less that if the 
tank were that filled with stem plants.  Also note that they dose small 
amounts, 2x a day.
