Questions about CO2 dosing

[ClamIAm]

I am currently working on the setup of a new planted tank and I have some questions about how you all go about CO2 dosing. I have not yet decided whether or not I will want/need to dose CO2, and don't really want to get into that discussion as I know it has already been brought up. The purpose of this thread is to determine what the best way to go about it is. For those that do dose it, what do you use? Are the kinds of products used in freshwater planted tanks effective in marine tanks as well?

The equipment is the same, but I would avoid CO2-mist. It feels like misting would act like a skimmer in the whole tank.

I'm sure you've already read this, but here it is, and a couple more.

Clam may actually be talking about Seachem's liquid CO2 product, Excel. This was a great thread discussing drawbacks of Excel in marine applications.

A typical and cheap setup for CO2 that the freshwater crowd still sometimes uses would be the yeast/sugar fermented coke bottle method. Take a 2L bottle, fill with water, sugar and yeast, and hook a line for the produced CO2 into the tank. Best if you route it through a water moving device.. I used to put mine through the intakes of cheap powerheads, which made a somewhat effective mist.

There are more professional and controllable methods, such as CO2 canisters, which I've been saving up for. They really aren't that expensive.

So the yeast bottle type device works reliably enough? I'm all for cheap solutions.
