In June I got my first tropical tank. A 48 litre 'Fishbox'. The day after everythin had settled I attempted a fishless cycle. The cycle was going until the end of July when I went on holiday. That is 60 days! Now the problem I had is this... at the start I topped ammonia up to 4ppm. It didn't move. Even 2 months later it had not gone down one bit. My test kit is indate. It is an API master kit. There is plenty of oxygen in the tank coming from the venturi. I added declorinator, I don't know why it hasnt moved. I got back from holiday and I am visiting family until next week, when I will be able to see if it has moved. Anyone have any ideas?
