Anyone know how you change to carbon on this filter. I couldn't tell from the description and the image isn't any help.

The carbon can be replaced, however most people don't bother or give it up because they don't pack the carbon correctly thus causing in-effective scrub. If you want to replace the carbon then here are a few tips...

- First the rivets need to be drilled out on the top or bottom of the filter. Do only one end.
- Get some good quality pelleted carbon
- Place a few inches of carbon into the filter carbon cavity. Tap the filter (up and down) on a hard surface, a concrete slab will do. Do this for a minute or two. This allows the carbon to settle correctly thus eliminating air gaps. Repeat this every few inches.
- Use expanding foam or neoprene on the top and seal the filter. The carbon needs to be compacted correctly so no carbon moves in the filter creating gaps.
- Re-rivet the end cap on (should be able to use self-tapping screws).

If it doesn't work you know where to get a new one (http://www.bghydro.com/BGH/itemdesc.asp?ic=AOCHHGOB06&eq=&Tp=). Hope that this helps.
