Hi
Anyone use Purigen?
I picked some up after reading about it here and think its great but seems to have turned brown fairly fast .
It was placed in newly set up 30 gallon and after 3 weeks (100 ml) turned brown.
Should I replace it at this color or it can still absorb more junk ?
My water is loaded with mineral its 8.2 ph right out of tap . Not sure if that has any bearing on it.
