I have a 5 gal. tank going that seemed cycled (0 amm. 0 Nitrites and 5ppm NitrAtes. I have a male Betta in it. Some Java ferns and anacharis. All of a sudden (after about 3 weeks) ammonia is 4+ , no nitrites and 5ppm Nitrates. Water is cloudy. Not sure WHY the ammonia went from 0 to over 4. Has me nuts at the moment. Been doing 1-2 gal water changes a day since. Use Ammo lock to help the betta out for now. Any ideas? Sponge filter. Temp 75 F.
Happy new year to all!
