Where is this ammonia coming from?
I set up my 10 gallon tank yesterday. I have some plants on mail order that I thought would get here by the weekend and didn't, but I had bought some locally and figured I should get those in and started establishing. When I tested the water yesterday, it showed about 1 ppm ammonia. This morning, I am getting about .5. There is no livestock in there. Just plants, driftwood, and rocks. I'm not overly concerned about it right now, just curious where it may have come from. Tap water tests at 0 ppm ammonia.
10 gallon rimless
Flourite Black substrate
Eheim Ecco Pro 60 canister filter
Dirftwood and rock hardscape.
Plants in there now are Stauraogyne repens, Alternanthera repens "cardinalis", Windelov java fern, a few sprigs of hair grass for accents, Anubias nana petite, and a couple moss balls.
