Ok ... there are three inserts that go inside this filter. I went to my LFS and found three different inserts for the middle layer. I usually use the Ammonia Remover but I'm wondering about the two other options. I currently have the Active Carbon since I couldnt find the ammonia remover last time I went to the store.
Zero Carb
Active Carbon
Which is better?
Also, with the top layer, Bio-Max, how many people buy the larger boxes that come with these carbon stuff and just use a bag for the top layer? I think it's cheaper.
