Almost too embarrassed to ask, but...
I have a 2215. It has the mechanical donut things in bottom, and the bacterial "balls" in the second layer. I just took my charcoal pad out based on 2 weeks of use.
I want to either get some floss or some peat to put in filter, maybe both. How does that work?
The peat is in granules. Do I buy a little mesh bag, fill the bag, and put in filter where charcoal used to be?
Or can I put the granules in the filter directly, and put a floss pad on top to hold them down?
Thanks for responses. I seem to be able to find every question about filters on the internet, but the one I am looking for!!!
