When is it safe for you to add fish - what level do the nitrates need to be at? How many fish can I add at a time? How do I introduce new fish to a tank? Should i change the filter cartridge I've been using (It's in the recommended amount of weeks before you change it) before adding fish? Also should i change some of the water? Sorry for so many questions xD
Thanks in advance for any answers!
