Yeast is quite different then a 48 hour magic cycle. Yeast is short lived once it is exposed to air. It has to mix with a sugar then ferment.
This product is suggesting that it contains bacteria that will contribute to the nitrogen cycle. A process that keeps on going. Much as "live" sand that is dry in a bag claims to. Add a bag of that to a tank and toss a fish in. Tell me that the tank does not cycle.
They make live sand that is dry? hahahaha
I got the caribsea sand and live rock. My caribsea sand was sold as live, it was WET, had water in bottom of bag after wet sand was empty. Was told dump water in that has lots in there. Like yeast, even though it needs sugar its still alive. So many types of bacteria on this planet. I doubt all is dead, and what does it eat? Well stuff in the sand and bacteria/orginisms that will die are food. Shelf life on a good wet sand I think rates how long till food is gone. Sand from ocean has so much in it. Brand sand should say how long its ok for, buy it new. 55g is going fast I think it was ok. (amonia went up, then lowered, nitrite went up then low, nitrate went up and amonia and nitrite are near 0) Nitrate still falling.
Sand bag should be wet, lift it and see if water settles in bag.
Just my thoughts atleast.
