My tank has been up and running for about 9 weeks now. I believe the tank has cycled, as my Ammonia and Nitrite are 0ppm and my nitrates have been testing 0-5ppm range for the past few weeks. I did notice a bit of a diatom bloom yesterday, but that may have been brought on by me (added new LED lighting & a 10g water change). I'm not too alarmed as that's typical at this stage and have experienced this with prior tanks. I'm planning on introducing my first fish and inverts this weekend, but I'm now wondering if I should let the bloom run it's course. Would there be any ill effect to a fish (clown) by introducing him during this bloom or would it not really matter?
