Ok, I'm reading and reading about all the options for filter cartridges/bag and what to do with them. (

) I have a few questions.
1) What is the difference between Floss vs. sponges vs. a pad?
I keep seeing this the Uncut Blue Bonded Filter Pad (
http://www.drsfostersmith.com/Produc...31&c=3578+4150 ) come up on the forums as you can just cut it and use it to replace your cartridges/bags. So here is my question ...
2) I have a Hex 5g that currently takes the Eclipse Z cartridges, so to replace this do i just cut a square and stick it where the little plastic and carbon cartridge went?
3) I also have a Tetra Whisper Filter for a 30 gallon that now has a bio-bag where you pour the carbon in the bag. So do I just replace this whole contraption with a square of the Filter Pad?
4) and where do floss and sponges come in? I'm not even going to ask about the little plastic balls I keep seeing as well! LOL
THANK YOU SOOOOO MUCH. You all pretty much rock!
