if little co2, use less plants to stop co2 competition?

okay, i dun really understand co2,
apparently its really important since my emersed planted tank
have been growing well compared to dead plants in my low tech fish tank.
(low lights, no co2.)

if i want to transfer plants from my emersed planted tank to fish tank,
should i limit the number of plants to stop co2 competition
between the plants?

how does co2 works?
besides the easy method of geting co2 from emersed tank.

I went the opposite way. I planted densely so that algae is more likely to be out competed for every kind of nutrient, including light.

A lack of co2 won't kill your plants in a low tech tank, it'll just slow their growth a bit. Since everything is growing slower, you really want to plant as heavily as possible to avoid problems with algae and keep everything balanced. You might also want to look into using something like excel.

I'm not sure I completely understand the question here; but I dont think limiting the number of plants in an effort to conserve co2 is anything that would really benefit you. Are you doing anything to add co2 to your setup?

Is it possible that the "dying" plants in your low tech tank are just transitioning from their emmersed (roots under water, plants/leaves above water) to submerged (entire plant/leaves/roots under water) forms?

yes im thinking of saving co2 by not planting heavily
which im not sure if it works.

im not doing anything to add co2,
and if possible i dun want to go with that way.

The more light you have, the faster the plants will try to grow. The faster they grow the more carbon they need to build their plant tissue. So, you reduce the demand for carbon (CO2) by reducing the light intensity. If the light intensity is around 20-30 PAR, the plants will get along fine with the CO2 they get from atmospheric CO2 that constantly dissolves into the water. More light than that and you will need to start using Excel or Metricide to provide carbon in another plant available form. Much more light than that and you have to use CO2 to give the plants the carbon they need.
