Test your pH - if it's low, then please raise it with baking soda (not baking powder) little by little, until the pH reaches 8.2. The other thing you can do is to get hold of some media from someone else's mature tank - swap it for some of yours, and the bacteria on their media will kickstart the growth in your filter.
I've just tested my tank pH and its at 7.4 (the same as my tap water). Is this a good pH level for cycling the tank? Why do you recommend a pH level of 8.2?
I might have to look into getting hold of some mature media!
