What is this cycling thing doing.
I know what cycling is. I have cycled a tank before.
...This is weird.
I've had my tank running with just water and a filter, no additives, no substrate, no ANYTHING for about a week now. I just hadn't gotten around to buying anything.
Yesterday, I tossed in a piece of driftwood that had been soaking in a bucket for a month, some floating plants from my other tank, and a palm-sized piece of driftwood from my cycled tank. I also dosed ammonia (Ace Hardware brand) to 2.5ppm. pH was much higher than normal for my city water at 8.3. I did not test for nitrites/nitrates because who does that on day one. No heater yet.
Today, I didn't change anything. Just testing. I was surprised when my ammonia went UP somewhat and my pH went DOWN dramatically.
Yesterday, day one:
Ammonia: 2.5 ppm
Nitrite/nitrate: Didn't check.
Ammonia: 3.0 ppm
Nitrite: 5.0+ ppm
I could understand a quick cycle if the ammonia went DOWN, but... the ammonia went up? What voodoo magic is this?
EDIT: SPOILER ALERT! The problem wound up being the National Geographic PF30 filter. It was kicking out tons of nitrites. No idea why.
Once upon a time I had ludwigia. It disintegrated.
