Hello, I'm trying to cycle a 10 gallon aquarium to use as a betta/cory tank for my son. We also have a 30 gallon tank that is well established and about 5 years old. I read exhaustively about this and thought I was doing everything right, but it has been 6 weeks with no progress. Here's the details: 10 gallon tank filled with tap water conditioned with API super strength tap water conditioner substrate is Carib Sea Tahitian Moon sand 75W Jager heater Filter - TruAqua PFE-1 - 15 Gal Capacity, 45 GPH Decorations - silk plants, floating logs, etc. I added Dr. Tim's Aquatics Ammonium Chloride to bring the ammonia to 4ppm (using API liquid test kit) From our established tank I used some decorations and some of the filter material (cut from a used Aqueon cartridge) that I stuck inside the new filter. Temp 80-82 pH 7.5 After that I waited for 4 weeks, testing frequently. The ammonia did not budge. I read some more and thought maybe the ammonia could be too high, so I did an 80% water change and brought the ammonia down to 2ppm. I also took some gravel from the established tank, put it in a mesh bag, and added it to the new tank. Now it's been 2 more weeks and the ammonia is not coming down. There have never been any nitrites. We're a bit frustrated! This is my first attempt at fishless cycling and it appears to be a total fail. Any suggestions? I know you get these questions all the time and I try to read previous posts/responses, but I don't know what to do next except just keep waiting... Thanks very much!
