Due to a combination of things like unexpected stocking of my tank (due to lfs mistake and leaky other tank), dying plant leaves (took out the offending plant) and stupidity by me (changing cartridge and vacuuming gravel in the same shot) my ammonia is up a little the last couple days. It's probably a little lighter color than the .25 reading. The first day I did a 10-15% water change, without disturbing the gravel. Today, the 2nd day, I did a 25% water change and just got the dead plant matter without disturbing the gravel much (as little as I could). If the ammonia is at the same level tomorrow I was going to do another 10-15% water change. But should I be doing them this frequently? Is there a reason that I shouldn't? I am pretty attached to all of my fish and don't want any of them to die but if doing these frequent water changes is a bad thing I don't want to do that either. Thanks!
