I am currently trying to fish less cycle my 20 gallon aquarium. I initially dosed the tank up to 4ppm with Ace Janitorial Strength Ammonia. I also treated the water with Seachem Prime and am running a filter. It is now 22 days later and nothing has changed. My ammonia is still at 4ppm and there is no sign of nitrites or nitrates. My pH is at 7.6 and has been that way since day one. The temperature of the tank is around 83 degrees. Unfortunately, I do not have access to any established media. It seems as though I should have some sort of a change in readings by now. Is this normal? Should I just give things some more time? Any help would be appreciated!
