How much whirfloc / L?

[BrosysBrews]

Hi,

Just started all grain, wondering how much whirfloc per L of water, only doing 18Lt batchs atm as I am using a BIG W pot for now. Used 1/2 a tab last time but read somewhere that 1 tab can be used for 1000lt or something like that so thinking 1/4 for my next batch?

1/2 a tab for around 20-22 L. In your case I'd stick with that for simplicity.

Its one of those things where 1/2 tab per 25l will work but 1 tab per 25l will not work better.
