Consequences of stopping using gas co2 vs. "liquid co2"

Ben777

Please, tell me if I understand it right.

I was discouraged from trying to use co2 gas system, when I read that if you stop using it, your plants are just gone and never recover. So I settled for a low-tech plant tank.

Then I read about "liquid co2", which has a much more gentle impact on the whole aquarium system.

I still have a question - what happens if I start using "liquid co2"? And what would happen if I stop using it? Would the consequences be as harsh as with gas co2 system?

Also, would you recommend using liquid co2 at all in nano aquarium? What are the pros. and cons.?

Thanks!!!

I don't think this is true; it certainly hasn't been in my experience. If you stop injecting CO2, you usually run into some algae issues, because the tank is balanced around having higher levels of CO2. But, all you have to do is adjust things to a low tech tank. The plants may go through an adjustment period, but I haven't found this to be any worse than when plants are added to a new tank. There are a few species that don't seem to do well in low tech tanks, and these of course would struggle.

...what happens if I start using "liquid co2"? And what would happen if I stop using it? Would the consequences be as harsh as with gas co2 system?
I've found using a product like Excel does help plants grow a little. Some say this is only due to the product killing algae...I don't know. If you stop using it, you may see a little slower growth and perhaps a bit more algae. I think it would depend on your tank. CO2 injection has a far greater impact on plant growth--plants grow 5-10X faster with it. So, stopping CO2 injection will have a greater impact.

Also, would you recommend using liquid co2 at all in nano aquarium? What are the pros. and cons.?
It's up to you. One can definitely create a beautiful planted tank without any such products. Pros: maybe slightly faster growth and less algae. Cons: an unnecessary added expense.

"Liquid CO2" is a misnomer. It's not CO2, it's a disinfectant that, for aquarium purposes, can double as an algaecide.

If you start with pressurized honestly you wont want to stop but if you have to just slowly dual it down over a month and your fine.

Ive done this when ive gone back home home for a month or 2 and never had a problem. Some plants have stopped growing or lost a few bottom leaves while i was away but nothing had gone wrong.
