I have a 10g
qt that I'm using for two false perc clownfish. They have been there for just shy of one week, ammonia is now up to 0.5
ppm. I feed once a day, they always seem hungry but they don't always catch all of the food, so I suck up remaining food on the floor nightly, at least as much as I can. I seeded a sponge filter from my main tank for 3 days or so before I introduced these fish, maybe that wasn't enough, or ammonia would have been higher without the sponge.
After testing ammonia yesterday, and finding it up to .5ppm, I did a 1g water change last night. Then I read some newsgroup forums. Some say do water changes daily, some say use chemicals such as AmQuel to control ammonia. Are both methods OK? What can ammonia go up to before I must do a water change?
