The title says it all...and yes i am using a dechlorinator. I live in the city, tank is 29 gallons, there is 6 zebra danio's in there, week 3 of the cycle. I use nutrafin brand water conditioner, label says it removes both chlorine and chloramine. Last water change was about 30%, and expecting to see the ammonia drop, it actually rose. Before water change ammonia level was between .25 and .50 ppm, and now its definitely over .50 ppm I tested the water coming out of the tap for ammonia before , and got 1ppm. knowing this when I did the water change of 10 gallons, I added 30 ml of water conditioner. Label says 10 ml is good for 10 gallons...what am I supposed to do? If water changes don't remove the toxins then what? Anyone else had this problem and resolved it?
