This is exactly what I did with my new cab. 30 cf. CO II with (so far) 3 lbs of beads on three levels. I'm getting 65 at the bottom and top hygros for the past 3 days. Seems to work well. The beads are around half clear half opaque white. I thought the beads would add "stabilizaton" and just in case for power outages and dunderhead non refills of the CO. Your spec says 6 lbs for this size humi. any value in my upping to 6 with this type of set-up?
With this size humi I would recommend the 6 pounds but you are not using the beads as the primary source of humidification. When using them as stabilization the 3 pound is pretty good. Just remember that the beads will desorb quicker than is normally desired but should hold the humidity long enough for the power to come back on or you get home from a trip, much longer in fact.
Now don't get me wrong here, if you want to buy 3 more pounds I will be gald to sell them to you. :r
