How Aquatic Plants Get Co2 In Wild?

[raptorrex]

I also have my plants with no co2 or additional nutrients

For people using no CO2, what are the best plants to use?
As i would like to put some plants in my discus tank, but don't want to use CO2
And for Vin Swords, i am finally getting some wild discus 1 tefe green + 1 japura green
May be here on saturday

I've been advised that these are ok ( amazon swords, hygrophilas, vallis, cryptos, java ferns & mosses, hornwort, and cambomba). but remember, they more light your tank gets, the more CO2 the plants need. so its a balance.

hey more light your tank gets, the more CO2 the plants need.

And nutrients as well

yep, good point
you know? i realised i should have mentioned that, just after i clicked the comp off after posting.

All three need to be balanced.

I never have much success with my plants despite being told I have adequate lighting by people on this forum and adding liquid ferts!

if I've got this right, you should be looking below adequate, (if you know what i mean) for a none CO2 system planted tank. more light, more food, more CO2 needed. and in reverse.

Well I imagine its like others said, some species are made to live in or out of the water and most comes from the atmosphere. Of course there are also species that can extract CO2 from carbonates in the water (esp hard water). I also beleive that there are probably types of bacteria that release CO2 in the water, plus you have to take into account fish aspiration they to release CO2. Also in the wild you have things that are are decaying and release CO2. I often keep a lot of the decaying leaves and such in the tank as they release CO2 and nutrients for the living plants, and my plants grow out of FREAKING control without any CO2 injection at all (I have to constantly cut them back). Plus in the wild its a chemistry thing, as CO2 in the atmosphere mixes with rain water to form H2CO3 (carbonic acid), which is mainly responsible for acid rain. When this runs into lakes and rivers and streams the plants can absorb some of this not to mention carbonic acid is exetremely unstable and will easily break back apart to form CO2 and H20.
