Re: [GSAS-Member] Has anyone had trouble with CO2 poisoning?

Dear Jeff,

The safety factor is that you have CO2 (and not the poison CO) and while we
try to get a concentration of 30 ppm in water, your room should start around
300 ppm.  A long time ago there was a calculation of releasing a full 5 lb
tank in a small room on the plantedtank.  Anyone remember the results?

I am with Jesse in thinking you have an ammonia problem (or something
similar).

Sounds like you have something going on if fresh air makes you feel
better immediately. 

You will be loosing some co2 from the surface of the water as well as
the overflow.  If you have a stable system that needs a continuous
bubble of CO2 from a tank to keep the CO2 levels steady in the tank,
that means that a continuous stream of CO2 is leaving the water
somewhere else.

I was just looking at the safety data for CO2 gas and the symptoms
listed all have to deal with oxygen displacement, including nausea.  It
lists the chemical as not being an eye or skin irritant.

On a hunch, I looked at ammonia just now, and that is listed as an eye
irritant.  So maybe you're getting something coming off as your tank is
still cycling?

Jesse
