View Full Version : Co2 Speculation

After reading an article (I forgot the URL) I found out that Co2 thats transfered into the water is based on how small the bubbles are. So I decided to revive my old canister filter and install it on the side. Now its spewing bubbles more fine then my air stone. Will this be sufficient for a tank that will later have a 3 watts per gallon lighting?

Nother question (I can't find the stupid edit button) Is there a way to put Co2 in the tank without the use of the actual gas? Maybe a supplement?

I think a bubble mist like you have will work fine, but you should get a drop checker to find out for sure. Also, yes you can use a suppliment for carbon in your tank, I think it will work ok for 3 watts per gallon in a 20 gallon tank:

But co2 is cheaper.

Fine bubbles are ok, but get a reactor for more efficient use of the CO2.

CO2 isn't what is needed by plants. Carbon is what is needed. Like posted, Flourish Excel is a carbon supplement, but CO2 will be cheaper in the long run and easier to manage on larger tanks.

Agreed. The cost of Excel is ridiculous compared to CO2.

The cannister filter is just hooked up to a pump. Nothing really new. That will do or do I actually have to inject Co2? Or could I drop carbon (LFS stuff) in the Aquarium?

That carbon you are most likely thinking of is a filtration media ( little black pellets ). Different stuff.

Oh. This stuff didn't look like media, as it was sold in 5 pound bags. I have a 20 gal, And lets say I use the 250 ml bottle (Flour-whatever). 2 ml a day, 175 days. less then a half of year. Roughly $21 a year. That I can handle. I don't really want to do the Soda thing, I am a klutz when it comes to sticky sugar water stuff.

If I want to grow Anubias, do I have to upgrade my light to 1.5-2 watts per gallon? I was going to get this fixture that gaive me 3.25 watts per gallon, but thats not economically feasible at this time. Should I just get an All-Glass (The current brand of hood I have) dual strip or get the 65 watt hood I originally was planning? (The All Glass is 36 watts total)

I grow anubias just fine in as low as .85 wpg. Once you get much over 1.5 - 2 wpg, algae on anubias leaves can become a real issue.

About the only light I've seen anubias not grow in is NO light.

The smaller bubbles in question are coming from a CO2 source.Not bubbles coming for a reqular air source.
