Hello, I've been cycling my 55 gallon tank since the beginning of March. I moved previously used filter media over, but I didn't fully understand the nitrogen cycle at the time, so that tank wasn't properly cycled. When I finally got a test kit and tested the water, the parameters were 0,0,0, so I don't think it was actually cycled. I found out recently that my tap water has 0.25 ppm ammonia in it. As per members' suggestions, I stopped water changes. I've been testing the water daily, and dosing Prime daily for the full volume of the tank. Today was the lowest the ammonia has ever been! Just the tiniest trace of green. However, seeing as I haven't done any water changes in awhile, I'm sort of surprised how low the nitrates are. I know that plants are supposed to keep nitrates low, but in the 55 gallon tank, I only have some hornwort; in a 10 gallon (which I'm also cycling) there aren't any plants! Yet when I tested just now, nitrates were 5-10ppm for both tanks, a bit less for the 55 gallon. In the 55 gallon, there is a BN pleco and three platys; in the 10 gallon there is a male betta. Is it possible the tank isn't actually cycling? Please don't say that I do shake the snot out of the second nitrate bottle (using the API freshwater master test kit, by the way); I actually shake all the bottles really well, just in case. But I'm confused as to how there could be so little nitrates when I haven't done water changes in ages, at least a couple weeks. Any information or advice would be greatly appreciated!
