Hi, just thought I'd share a little trick I've discovered. I've never
come across anything about this, and if anyone who reads this has, I'd
love to have the link.
I live in central Florida, and my 55g aquarium is on an porch which is
enclosed, but not heated or cooled. Of course I heat the aquarium, but
have had problems with my diy CO2 production fluctuating with the ambient
temperature. When it's in the high 80's on the porch, tons of CO2 is
produced, and when it's in the 40's virtually none is. My solution was to
build a little wood shelf that allows the yeast mixture (which I keep in
three soda bottles) to sit up against the aquarium glass (behind the
aquarium which also keeps them out of sight). I then built a little
enclosure out of leftover insulation board that goes around the other
three sides of the bottles along with a little insulated cover so I can
get to them for maintenance. Voila, the bottles are now kept at the same,
relatively constant, temperature that the aquarium is. It has worked
great so far, my CO2 production is wonderfully consistent now. I'm gonna
feel really stupid if you guys send me 5,000 links of sites that describe
how to do this, or mock me for not having a pressurized system, but oh
well. I felt like sharing Allison

Sounds like an excellent idea to me. I've been around the plants sites and
haven't seen this mentioned, so you may be onto something...congratulations.
