Im new and currently cycling a 120l tank and i'm confused there are many different kits and some say NO3 and NO4 kits and I don't know which one/s to get. At one of my local pet/Aquarium stores they said I only need ammonia and ph but in the information section here is says you need nitrogen testing kit/s as well. So can anyone assist me with this query?
