Ok... I set up my tank approximately 14'ish days ago. I tested for ammonia and it was high, so I did a water change. Took out 40% of the water to be on the safe side... I used Kordon Amquel+ removes nitrate, nitrite, chlorine etc. I test the wter this morning ammonia level went down but still not in the normal range. How can I reduce the ammonia level? Also, I have Kordon Amquel+ Ammonia Detoxifier, should I add this to my tank or is that to much?
