Hi,

I have some questions about the filter media in my top filter.

Below is the filter media that I currently use :
Top layer : Green Floss
Second layer : Active Carbon
Last layer : Bio - Foam

Is my arrangement correct and what is the proper sequence of layer?

You don't need/want the carbon unless you are trying to remove medication
from the water. It will pull everything out (including any plant
fertilizer). Also it will last a maximum of 2-3 weeks before it stops
working - after that it just becomes extra bio-media.

I.
