I do a 25-40% water change about 2 times a week.
after 2 days the water gets really cloudy and the ammonia
levels are the worst. I check the ammonia content of the water
before I added it. There is none to speak of. I have a couple plants
rocks, and thats it. What could be causing this? I hate to use chemicals to treat it,
but what can I do to prevent this spike in ammonia?
