Hey! I've been cycling my first tank. I dosed with ammonia and added Bio Spira. My ammonia levels are going down. When they read 0 ppm do I need to does again until it goes down 2 ppm in 24 hours? Or when it goes to 0 ppm am I cycled? Any help would be appreciated and thanks to this forum for being awesome.
