<div>Steve,</div><div>I read somewhere that the scrubber needs to be two times as tall as it is wide. I have followed that rule ever since. Then the theory about as long a soak time as possible comes into play. My feeling is that that is only important with a closed system like a re-breather. I base that on Gamma's original scrubber witch was about 10 inches in dia and 6 inches tall with an open top and a hurricane force fan drawing air through it. It makes sense to me that it does not matter how long the soak time is in a submarine environment as long as you have air flow over the media. I would do what you have to to make it fit, then play with flow rates. The key to a good scrubber seems to be to use good media, like Soda Sorb HP</div></div></div><div><div style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div>Hank</div></div></div><div><div style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div><br></div>
