I have a top fin 30 HOB Filter that I am noticing the filter pad need to be changed. I bought new one last night. I have the Type with the blue foam pad in front of it for bacterial growth. I just want to change the white pad behind it. I am wondering if I need to "seed" the new filter or just change it out? I also have the Eclise 3 Filter in hood system and the filter needs to be changed in it also. Do I need to float the filter even though it has a bio-wheel?
Thanks
