marc,

as i recall, salmonids are more sensitive to ammonia levels than tilapia & 
you might want to monitor TAN levels closely while you get things in 
balance.

as for socks, you may find yourself checking for holes a lot of the 
time--are other filter or settlement techniques out of the question?  a 
settlement tower or channel might give you an lower maintainence solution.

you've had an interesting chat w/ron.  you might want to compare the two 
systems based on load as well as density (quick refresher---density = 
weight/volume (kg/m3 or pds/ft3): load = weight/flow (kg/liter/min or 
pd/gal/min).  it seems to me that salmonid culture tends to rely on higher 
densities but lower loading than tilapia culture.  just a thought.

I am working with rainbow trout and char ( their gills are extremely fragile 
to high TSS), . . .solution I want to try is to control the amount of time 
the "waste" will be in the water using a sort of sock/bag. >Marc Laberge

Hi Bob,
Guess you better repost your questions. Sometimes things do get lost in
the rush..
