<div>Thats good news on the shelf life of the absorbent. Ive got 6 5L canisters and was worried they were going to go bad. Looks like they will be ok for a while yet!</div>

<div><span>James,</span></div>
<div><span>Thank you for the clarification. I was also surprised that the co2 level was in the neighbourhood of 5,000ppm when I turned the sensor on. I assumed the air quality would be better with the hatch open while I tinker inside. I hooked up my shop vac to the flood valve to suck clean air inside before I started my test.</span></div>
<div><span> Carsten mentioned one time that he has used 20yr old absorbent. Gamma came with full bottles of absorbent that have to be around 20 yrs old. I experimented with the old material and it worked the same as new stuff. Talk about shelf life.</span></div>

<div>Hi Hank,</div>
<div> </div>
<div>Ive got one of Emiles scrubbers. Holds the sub at 3200 - 3500 and i find this quite ok. I did try an experiment (on land with an assistant watching) where i let CO2 get to 7500 - 10000ppm for about half an hour. I could tolerate this just, but i wouldnt like it to go any more.<br clear="none">
