I had the same issue, even using neat thin bleach from the supermarket the Purigen was still a light brown colour suggesting not all the organic material had been removed during the recharge.Hi all,
I'm just wondering what bleach people are using to recharge Seachem Purigen, as I'm struggling to find a simple bleach that's suitable?
I leave it soaking for 24 hours, shaking the tub occasionally to circulate. Then I drain, rinse and repeat just to be sure.Was wondering how you clean the purigen after soaking in S. Hypochlorite, I use this stuff to clean block paving slabs and the data sheet advises it is lethal to aquatic life!
How long do you leave it in Prime
I change my mind. Ignore my comment above!With anything like that you need to let it dry thoroughly too,
