Currently, I am trying to do a fish-less cycle(5gal) and could not get the process going with shrimp. I did a few water changes over a few weeks after removing the shrimp and tried Stability to try and jump start my cycle.
I cannot seem to get my NitrItes(5.0ppm) and NitrAtes(40-80ppm) down. My ammonia is at a steady 0ppm since Stability with PH of 7.4. Any help/suggestions would be appreciated.
I do have a second question, When should I change my filter for my tank and is there more then just replacing old cartridge?
