Is it possible to make/mix a huge batch of the recipe without adding water and store it and use it over time?

 

[Sotty]

You could, but over time the yeast and sugar mixed dry will likely start to separate to some extent leaving the mix non - homogeneous. This would be a big deal if you gave it a good shake before scooping each time. Also if you are to be mixing up more than a couple months worth, I would keep it in the refrigerator as it will keep more of the yeast viable.

Like Sotty said...I wouldn't. Yeast is best kept sealed, cool, and in a dark area. I keep my open yeast packets in a ziplock in the freezer.

Your best bet is mix as needed. Unless you are creating mixes for individual containers, but I still wouldn't recommend that. You can't accurately just mix up a bunch of sugar and yeast and expect to scoop it out as needed and have the correct amounts of each.

You can put your baking soda and sugar into sandwich bags and just dump those into your bottles as you need them. Add yeast and water and you're good to go.

^ that might be the best solution. This is for when I have to leave my tank for a long time with someone else. I don't want to make it very complex for my fish feeder.

I've not found a real "need" for baking soda and don't use it but experiment and see what works for you.
