Okay, I'm having a bit of a crisis.
Tank has been up for nearly 2 months now with a single betta in it. 5 plants.
Ammonia levels were zero and trites and trates were zero.
So, I add 3 plants yesterday, and 6 cardinal tetras and did a 50% water change.
2 died overnight. So, I test the water and my ammonia levels are THROUGH THE ROOF. Like over 8 ppm. I just did an 80% water change, and added a 50gal dose of prime. Will re-check ammonia later tonight.
What gives? Why did it spike so high all of a sudden? I don't use Windex or any chemicals around the tank (and there are none in the house on that level), and I used the Aqueon water changer to change it. I tested my tap water and its levels were between 2 and 4 PPM, so I don't think that caused it.
Any other ideas on why it spiked so high? Will update with levels later.
