Question help, homemade co2 problem

undefined

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.

Thanks,
Tish

I am only a newbee algea grower - but am getting really good at growing algea quickly. I have home brewed a bit - so at liest I understand some of the dynamics of a diy co2 system. I wanted to do one myself, but the hive talked me out of it....

One think I would seriously consider is a diy bublle counter. It consists of a small bottle with two hoses through the cap (one short - near the top, the other longer, near the bottom - below the water level).

From beer exp., sometime foam will travel up the hose, the second chamber should catch this - and give you a good idea of co2 production as well.

Oh, a check valve is also a good idea - if the yeast bottle does not have much gas production, and the tempreture drops, it will suck water down the hose.

Anyway, I am new at this, so please disregard any of this rambling when experianced people give better ideas.

Put a check valve in the tube running from your CO2 to your pump so your tank water doesn't fill into your CO2 mix. The pressure of the CO2 build up will push out the water from the tube, no problem. Just wait a day for it to start producing CO2 and push out all the O2.

Hold on a second here.

Pond. How large of a pond? How are you lighting it?

Floating Heart. What is the real name of this plant? Do you have pictures?

If it's a floating plant then CO2 in the water column is not going to help it at all.
