So I think my tank has finally cycled, though I'd love confirmation. Ammonia is 0, Nitrites 0, Nitrates are a little more orange than the zero but not quite as much as the 5. Does this mean I'm good to go? I know it's not great if there are no nitrates unless the tank is "heavily planted" but I'm not sure how to interpret that. I do have plants in the tank. Can I add more fish now?? Also, after a couple days the tank water takes on a yellowish color, any idea why that is, and how to keep it clear without increasing water changes? I've been changing the water 2-3 times a week (or more) and I'm looking forward to less frequency on that. The tank is 29 gallon and currently houses 4 platy, 3 guppies, and 2 red cherry shrimp. Oh also how often should I be checking the water now that it's (presumably) cycled?
