To regenerate: Dissolve 4 cups table salt in 1 US-gallon of room-temperature water per 250-ml of resin to be regenerated in a clean pail; place resin into pail and stir; allow beads to soak overnight; strain and rinse beads thoroughly in fresh water before re-using. Do not regenerate with bleach, which will damage resin and could kill aquarium inhabitants.
簡單說就是要攪拌,然後置放過夜,再換新水沖洗!
