what bottle for co2 DIY?

[guppygirl]

Hi, I just had a quick question. I have a gallon container for my DIY co2 on my 55 gallon, because I have no access to 2Liter bottles, is this too much, and if it isn't what recipe should I use or should I just double one?
Thanks,
Robin

I use one 2 quart container right now then in a few days I'm going to add another so I can switch one out without affecting the tank. So I would assume you are fine with using a gallon.

so what 'recipe' should I use?

Well you have 1 gallon which is 4 quarts so just double the recipe.
