how does the charcoal work? Do i just buy the charcoal pads and change them with foam pads that it comes with? Or?
You can do one of two things:
1.) Buy a big plastic container of the "fluval" brand charcoal which comes with a small re-usable nylon bag for your charcoal (more messy, way less expensive since you can buy charcoal in bulk).
2.) Buy the fluval-brand charcoal "pads" that fit inbetween the sponge pads (less messy, more expensive).
I chose option #1 for my fluval filters (I have two fluvals: the fluval 4 & 2) because it is cheaper to just buy a gigantic tub of charcoal rather than buying the little charcoal pads. So I use the 2 white sponge pads & a small bag of charcoal inside the filter. The good news about the charcoal is that you don't need much.....I use maybe 5 teaspoons of charcoal inside the bag, roll it up (no need to tie it), and place it between the sponge pads when you put the filter back together. I replace the charcoal every week since it absorbs nasty chemical stuff from the water (chlorine, turtle waste, etc.) & helps the water stay fresh/clear. Don't re-use the charcoal. The white sponge pads ARE re-usable....just rinse them out in the sink weekly since they grab onto large stuff like when your turtle sheds skin.
The charcoal I use has some ammonia-eater stuff in it (charcoal + ammonia eater mix). You can tell it has the stuff to absorb ammonia because it has white particles mixed in with the black charcoal. Ammonia comes from when your turtle pees. So if you can get the charcoal + ammonia stuff, it's better for the water quality. AND it isn't much more expensive.
