I started up a new 26 gallon tank and used Amazonia Light for the substrate along with power sand and the supplement packs (Bacter 100, etc). The tank cycled and I now have plants in it. Everything seems to be going well so far. I'm injecting CO2 and I've been supplementing with Seachem liquid nitrogen (half a cap twice per week) and Seachem Flourish twice per week. Plant growth is good and algae thus far. I'd like to add some mystery snails and Amano shrimp in the next week or so. My question is, since there has been no ammonia source in the tank, so I need to force a mini-cycle before introducing livestock?
