how to stop with CO2


I have a tank that I have a bunch of plants growing in right now. I plan to grow them out to a desired look. So I am using CO2 to hasten the growth. But I know if I stop using CO2 there will be all sorts of algae problems. So my question is, how can I stop the use of CO2 once it's grown out without all these problems?

Why would you want to stop the growth once you achieve the desired look?

You can slow down growth by reducing CO2 and fertilization (as well as reducing light intensity), but you will not be able to keep the aquascape static permanently. Only regular maintenance (pruning, etc) will keep the aquascape neat and maintained.

Drastically reduce the lighting.

Its not that I want the desired look, its more that i just want the plants to be grown out more. Right now they're really short because they were top trimmings from a rescape. I also have very little lighting on this tank. I'd say its about medium light. its one fuge ray for a 30 cm cube tank. would a black out work?

Lighting is your monster.
2nd burr740 on this one.

Remember the look you achieve will change.
Many plants grow different with less lighting and no CO2.

Also +1 to burr.

Light is always the primary driver of growth. Tone that down and you can start turning down your CO2. Take it slow - if you make a large change overnight you could have issues.

Where did you learn that's true?

Yeah I am also quite sure that if I stopped CO2 without changing my light levels my high tech would blow up with algae
