Hey, I have a question about cycling my new used tank.. I understand the cycling process, have successfully cycled 2 10g's. So here's my scenario, please let my know your views and opinions.. I bought a new used, 33g tank. The former own had it up and running for about 8 months. there were fish in it, and they were all looking good, he said he had no issues with them.. So i naturally assume the tank is established. When we emptied the tank for transport, i left the water just above the substrate. and kept the filter media submerged in tank water. Once set up at home. I added Cycle for 3 days (as the bottle says to.) As well as adding some established filter media from a 10g i have into the AquaClear300 that came with the new tank. I have 3 zebra danio's, 3 platy's, and 2 neon tetra's in it.. My last two water tests came back; Ammmonia - 0 Nitrite - 0 Nitrate - 10ppm Hardness - 105ppm Chlorine - 0 Alkalinity - 110ppm pH - 7.0-7.2 Is it possible that given the circumstances of the tank, and bacteria that I had an extremely fast cycle? Any advice/thoughts/opinions would be much appreciated!! Thanks!
