I gave up on carbon. Yes we can see a bit of difference here and there but is it worth the hassle? Not sure. Considering its short term effectiveness definitelly makes us doubt it.

Wish BRS did a test on its efficiency in a month or two so we could have results back what we think though.
Purigen and that other renewable stuff never gave me any results. I think any snow white bead product we place in a bag inside a tank will turn brown through time and look like its dong something. I know many swear by it.
