Sorry to bud in, but I have found no negative side effects of not using any buffer during the regeneration process. I just use a bleach 1:1 water solution, keep the Purigen in there for 24 hours. Wash thoroughly, then I let it sit in some tap water for a week. Rinse again, make sure there is no smell of bleach. Add to filter, fish are doing fine. No rise in pH, infact I tested the pH of the water and it's actually lower than 7 (0.01+/-). |
