Hi,
I've been cycling my new 180 litre tank for about 6 weeks. But it still hasn't cycled yet, I added pure ammonia to start the process, my nitrite levels then picked up and I now have nitrate levels currently around 20ppm. The problem is the nitrite levels are now zero and ammonia stays at around 2ppm.
Shouldn't the ammonia be at zero by now, any help and advice would be greatly appreciated.
