Cycle Question - I'm on day 10 of this fishless cycle of my Cadlights 70g Artisan reef tank. I'm using the AlgaeBarn rapid cycle kit, which contains Fritz Turbo Start 900 and Algae Barn Nitrocycle from BRS. First 6 days ammonia was 3/ppm and N02 and NO3 was 0/ppm. No tests day 7,8,9 (life got in the way). On day 10 NH3 and NO2 was 0/ppm, but the NO3 spiked to 20/ppm. I used the Red Sea and API test kits. Do you folks think I missed the NO2 spike and it's time for a big water change?
