I recently set up a 29 gallon freshwater tank. The friendly guy at my LFS
offered to give me a bag of bacteria to "get me started." (He shook out a large filter from one of his tanks.) So, I started with three sunset fire platies (and the bag of bacteria) and never had the ammonia or nitrite spikes I was expecting after reading about them in a book and on many websites. Every day of the first week my readings were ammonia 0, nitrite 0 and nitrate 0. LFS
guy said I could get more fish so I added 3 zebra danios a couple days ago (with the intention of getting 5 more soon). Readings are still 0, 0 and, now, nitrate 5ppm. Am I missing something or did that bag of bacteria really do the trick?
