Its been many years since I last used a Aquaclear filter, but I am puzzled as to why you need the ammonia removal insert. The plain foam is to remove particulate matter from the water (and it provides some biological action as well), the carbon is to remove toxic substances in the water (if any), and the biomax stone insert is to provide a large surface area on which the bacteria will grow that provides the biological filtering, most important. As the bacteria need ammonia, I don't see why there should be an amonia remover, it seems to be defeating the purpose of the biological filtration. I would suggest leaving the ammonia insert out; it could be used should you ever have an ammonia spike due to some catastrophe, but let's hope that never occurs.
Others with more experience with Aquaclear may have more to say. If you want to find out more about the nitrogen cycle, you can have a look at my post in this same forum under the topic "I'm a little concerned", my response of 04-02-2009 at 3:07PM explained the cycle in detail. That may better explain why I'm suggesting you remove the ammonia insert.
Is this a new tank, or one that has been running a while and is fully cycled?
