Hey guys
So my Seachem purigen is still sitting in its bag in the sump and after 8 months it's still basically white. The only colour change is the bag has some coralline growing on it. I think it maybe still working as between it and my refugium my nitrates are 5-10ppm at most, 0-5 after a water change.
My question is anyone else have this happen? Shouldn't it be turning brown? How long does yours last?
