Unlike Fermaid K, SIY 33 (Fermaid 2133) does not contain added ammonia salts (DAP) or supplemented micronutrients.
In order to avoid CO2 release and overflowing of fermentation vessels, SIY 33 (Fermaid 2133) should be mixed with room temperature water before adding to an active fermentation. The amount of water used is not critical. Simply add enough water to make a slurry.
