Around midday today I did a 50% water change. I rearranged a bunch of things in the tank (rocks, clay pot, fake driftwood, fake plants, etc.), then re-filled the tank. I didn't add anything, just moved things around. Everything seemed fine and the fish seem content.
About 6 hours later I tested the water only to find a small amount of ammonia. Nothing crazy - less than .25 ppm, but there nonetheless. Everything else is exactly as it should be: pH 6.8, Nitrite 0, Nitrate 10 ppm. The numbers have been identical every time I've tested during the last month, except today. I forgot to test before the water change, but I tested 2 days ago and everything was perfect.
Could this have come from moving things around? The only other thing that has changed is that I moved my filter intake to the same side as the outflow, but I can't imagine that would have anything to do with this. I know it's not a large amount, but given that I've never had any ammonia show up in the tests, this has me concerned.
Thoughts?
