help, homemade co2 problem
Hi, got a problem, wondering if you can help me out. I have a little pond in my living room where I planted floating heart. I built a co2 generator from a soda bottle, stocked it with yeast, sugar, and baking soda. I made a reactor out of a submersible pump, siphon, and foam (like I read about on this site) but the tube from the soda bottle to the reactor keeps filling with water. Can co2 make it from the soda bottle to the reactor if the tube is filled with water, or do I need an empty tube? Also, pump does not seem to be doing much to the siphon, I don't see any bubbles etc. Please advise, I love my little pond and want my plants to flourish.
