I just started a new 20 gallon tank and used Bio-spira to seed with
bacteria. I setup the tank Saturday and added fish (5 inches worth) and
Bio-spira on Sunday. On Monday I added another 6 inches worth of fish plus
a few MTS and ghost shrimp. My ammonia indicator hasn't shown a trace of
ammonia yet! The tank also has a few plants, but these are brand new, so I
don't think they're growing enough to consume all the waste.
