This is the first I am hearing that the smell of our tank could indicate we are not cycled. We went purely by the water test results. Our amonia spiked and then leveled off, our nitrites spiked and then leveled off. We did the water change, had our water tested at the water store to double check our results and added 2 clowns and crabs - which are doing well too.
We did 1 water change last week and the smell is getting better. I beleive my canister filter does already run charcoal.. do you mean to run more? I'm confused.
