I'm not trying to cut corners, I have 2 established filters working on a large tank which will be transferred to this new tank, and thought it would save time not having to wait for the large amounts of ammonia to leech out.
But then the tank would be devoid of bio film which is a shrimps main food source. Shrimp do well in an aquarium that is established, not a brand new clean setup. What I'm saying is, the 4-6 weeks of cycling Amazonia is a good thing, not something that should be skipped. Plus it's the best soil for these shrimp. Ask the person who is selling the TBs to you, they probably are using Amazonia as well.
