hi everyone, I've been cycling my new 55gallon freshwater aquarium for 3 weeks now, i have a 20gallon freshwater tank that i'm planning on moving those fish into the new tank. I put a little bit of sand from my old tank to the 50g, a marimo from the 20, artificial plants and rocks from my 20g all into the new 55 gallon. My 55 gallon is a planted tank. When I first set up the tank I added stress coat, stress zyme, prime and a ph buffer. I am trying to do the fishless cycle, I let that run for about a week and then I went to the store and picked up quick start and dosed the tank with that and then added fish flakes every other day for about 2 1/2 weeks. Ive been testing the ammonia but i didn't test the first week so i dont know if the ammonia spiked or not however everytime i've tested for ammonia it has been 0-0.25 and nitrates and nitrites are 0 from what I could see. Does it sound like it's cycling right? should a add a danio or soemthing to help the cycle? or Should I just take the filter off of my other tank (the 20g) and just put that on my new tank along with the 75g filter thats on the 50gallon tank. And if I did put the old filter on my new tank my fish should be able to go right in correct? because the bioload would be the same as on my old tank? Also my water on both tanks as far as temp, ph and hardness are the same.
