Hi,
Nothing to do with water changes, i completely understand the cycle and i am mainly looking for removal of tanning, odors etc
i have anerobic filtration chambers in my tank, custom built of course but they work well

as I said before I am looking to remove tannin, odors and get that polished look that carbon gives without using carbon! I have currently got purigen in a reactor in line with my eheim 2217 and it does not seem to discolour as it should when i reaches capacity, it has been in there 3 months and not changed one bit!!

do you have any advice as to why it is not working? or does it not have to discolour before it needs recharged?
