I don't have any Vodka or vinegar around, but I have some gin (or single-malt whiskey which I don't think the bacteria would fully appreciate the taste of). Can I dose one of those? I'm not looking to carbon-dose long-term, just kickstart some bacteria cultures I have going and remove some nitrates before I toss in my first batch of fish.

Thanks!

The carbon source in vodka is ethanol. If the proof (essentially, the concentration of ethanol) is similar between your gin on hand and that of typical vodka (~ 80 proof or 40% by volume), then dose just the same as you would with vodka. If the gin's proof is significantly higher or lower, then just adjust accordingly
