Its been 4 weeks since I setup my 75 gal tank and started my fishless cycle. Its my first attempt at it so I spent an insane amount of time researching before I started. I followed all the basic guidelines laid out by various posts on the forum. My problem is its been 4 weeks and I still have no decrease in ammonia level (which is at 4ppm) and no trace of nitrites. I used stress coat to remove the chlorine after filling and even let it set up and running for 24 hours before adding the ammonia (100% hardware store ammonia). I'm using API master test kit which is only a couple months old, to take my readings. I'm not really that impatient with it, I just would like to know if this is normal. After searching all over the web i'm having trouble coming up with people that have had a similar situation. Any advice would be appreciated. Thanks.
