co2 room temperature

ok im trying to do yeast in my basement fish room- only prob is im getting about 1bubble per 2 seconds or maybe even 3. ive treid about 3 different batches so i dont think its my mix. what i think it might be is its colder in the basement (so my wife says i think it feels nice) but how much will that effect the contraption. ive read that wine yeast can work at lower temperatures but how low? can wine yeast work at around 63'f

any ideas would be great

I'm not sure of the "operating temp" of yeast, however I did run across a suggestion on a way to compensate this problem. This will also help reduce 'night spikes' of co2 concentration. What you do is set your homemade bottle(s) into a small bucket and fill that bucket with some water. Place an aquarium heater in the water and put it on a timer. If you have a timer for your lights, put it with them. That way it will heat it up during the day and encourage the yeast to get to work. And at night, it will cool down, especially in your basement, reducing an overload of co2!

Hope this helps!

Champagne yeast works at lower temperatures.

  • 150g dirt tank (work in progress)
  • 100g corner community tank
  • 180g Native North American fish
  • 85g bichir lair
  • 45g flatback hex dirt tank
  • 75g blackwater tank
  • 40 breeder dollar sunfish

as a homebrewer i've struggled with this problem. temperature does influence yeast activity. with some of the yeasts i've used before (mostly ale yeast) a difference between a few degrees f will mean the difference between a beautiful, well fermented ale, and a 50$ batch of warm, beer flavored sugar water.
im pretty sure bread yeast is pretty resilient, you could try switching to a lager yeast if there's a homebrew store around- they prefer cooler temps.

IME - Temeprature was a huge factor in even CO2 production. I would try putting the yeast bottles in a water bath, but a I would try something like a rubbermaid tub versus a bucket. Also, I would heat it 24/7 because it takes the yeast some time to get going after it warms up. Even CO2 levels have always worked better for me than constantly flucuating levels.
