[Greenbuilding] surface area

[ARCH59 at aol.com]

What about actual real stones collected from sites?

in our  region, recycled, crushed concrete is available in several popular  
grades.  not very lightweight, but I imagine the surface would be microbe  
friendly.

this does however, raise the question of PH, due to the  alkaline nature of 
portland.

Foam would be a great colonizer but I want to stay away  from synthetics 
given that it is a long term swimming pool and I don't want  to worry about

Hi 
Your  talking about a biofilter and foam chips have been used successfully 
for  that in all types of wastewater treatment for maintaining a ‘smutzdecke’
  (waterloo biofilter is one example) though typically it is graded sand 
and  gravel. Netted bags of foam chips with some kind of ballast might work  
well. Lots of research out there. 
Best

I am building a natural pool and could use some insight  into the media 
used in the regenerative zone. 
 
Typically gravel is used since it creates large surface  area for microbes 
and lasts.
 
Ideally I would prefer something lighter so it can be  more easily removed 
when the pool leaks.
 
I considered crushed brick but dust could be an  issue.
 
I salvaged some Spanish S tile I could put in and cover  with gravel. I 
wouldn't break it I would just put it in the way it comes  stacked on the 
pallet. Any thoughts on how that would compare to gravel in  terms of surface 
area? Keep in mind that microbe surface area is different  than surface area we 
can see.
 
Using safety netting from job sites would have amazing  surface area but I 
am not interested in the leeching  possibilities.
 

 
Any thoughts?
