[Killietalk] polyfilters

[Paul Jarvis <pjarvis at uidaho_edu>]

Greetings everyone.

I have been reading the thread on the poly filters.

I have never tried it, but have known of it for many years, I think it has
been around for at least 15 years.

After reading Bill S. comment I thought I might make an observation here. 

Beware, there are absolutly NO flames intended and no criticism intended,
this is only an observation.

As I read through Bill's post he said:

" I bagged them in my garsage and don't smoke when bagging."

Bill said he does not smoke "when bagging".

Assuming that Bill smokes, perhaps there was some nicotine on his fingers
which was picked up by the polyfilter and released into the water with the
fish?

I had a technician that worked for me, he smoked very heavily and his hands
were very stained from smoking, I often worried about the amount of nicotine
that was being washed from his hands into the tanks of fish.

Nicotine is VERY toxic. When I was a teen, a friend of mine and I went
rattlesnake hunting. My friend chewed tobacco. He caught a rattler and spit
some "chew" into its mouth, the snake went into convulsion almost immediatly
 It started bleeding from the mouth and was dead in about 5 minutes. Whoa,
that convinced me as to the toxicity of nicotine, (or else my friend had
really bad saliva) ;).

So, just remember this is not an attack on smokers, this is just an
observation.

Shields up!
