My 57g has been up and running now for 2.5 weeks. Live Carib Sea, dry rock (Marco Rocks), and used instant ocean bio-spira along with a seeded rock from another tank in the sump. Had my ammonia spike and no diatoms. I tested my water for the last 3 nights and I am at 0 ammonia, 0 nitrites, and .10ppm nitrates. Just for peace of mind as it has been a long time since I have cycled a tank, I am safe to assume that the tank has cycled without a diatom bloom? I know that this will come at some point, just wanted to see what you guys thought.
