I am currently cycling my 15 gallon fish tank. I could not locate any pure ammonia, so I have been adding fish food daily to the aquarium. The filter that will be on the aquarium is due to arrive any day now, but the ammonia still has not spiked in the tank (it has been 1 week now). My question is, will the carbon in the filter affect the cycle? Should I take it out, this is my first canister filter so I don't really know how it is set up yet. Also, my tank looks full of fish food but there is still no sign of ammonia. Is this normal after this amount of time? I leave the light on, have put an airstone in, and the temp. is always in the high 70's. I did all of this because I read that it will help to accelerate the cycle. Am I doing anything wrong? Thank you.

Does anyone know about using carbon while doing a fishless cycle? Any advice would be appreciated. Thank you.

I always remove the carbon from my filter media. It removes nutrition from the water that plants need to survive, and leaving carbon in your filter for to long has been known to cause hole in the head disease.

And the carbon can soak up some of you ammonia, and since you want ammonia in the cycling process, then yes I would remove the carbon. Not the actually media for the filter, just cut along the flossy side of the media, and shake all the carbon outta there and then boom! You have yourself a reusable filter media, Just take it out once a month give it a good rinse and you can put it back in. I hope this helped.

Thanks, that's what I thought. I'll definitely take it out before I put it on my tank. Thank you.
