Hey, can I please have some advice. I have been cycling my 7.5 gallon tank for the past month or so, adding 4 head and tail tetras. I am still at the Ammonia stage maxing to .5ppm making sure to drop Ammonia levels below .25ppm, changing the water every other day with Seachem Prime to control the Ammonia levels. I have also added some Interpet Quick Safe Start per water change along with Prime as advised by my petshop to quicken the cycle. Also following the packaging to use with some hardy fish. Testing with API Master Test Kit before and after water changes and testing every day to ensure it was below 1ppm, it's always stayed at .5ppm before the days following the water changes. Yesterday I had left it around 4 days and Ammonia levels were at 1ppm, doing a 30% water change bringing it back to .25ppm, today was similar back up to 1ppm and did a 30% water change and added the recommended dose of Seachem Prime and Quick Safe Start. But it remained at 1ppm yet no signs of Nitrites... I have been feeding them sparingly, once a day small incriments and will start cutting back to every other day. Can someone please advise me? What am I doing wrong? After reading endless posts and reviews I have just bought Fluval Cycle Biological Enhancer and API Ammo Lock 2 but I don't want to add anything else until I know exactly how it should be dosed.
