8 Steps To Recharge Purigen
Step 1: Keep all the ingredients and complete the setup in one place for performing the task to rejuvenate the purigen.
Step 2: The first thing is that you have to make a bleaching solution using tap water. The bleach ratio to the water is a half cup of bleach to a half cup of water.
It is not necessarily half cup to half cup ratio. You can use the water accordingly with the amount of bleach. But both should be in equal parts.
Step 3: Abstract the worn-out purigen from the filter and dip (submerge) in the mixture/solution you just made.
Step 4: Now, leave this container with a submerged bag of purigen for 24 hours in a ventilated area away from the reach of children and pets.
Be sure not to forget to flip or overturn the purigen now so that all the purigen in the bag is well exposed to the bleach.
Step 5: After 24 hours have expired, you can remove the container’s purigen bag to rinse it under the running water.
Step 6: Now get back to the container containing bleach solution, drain all the solution into the sink, and rinse out the container. Wipe it with a clean towel and fill it with a cup of water.
Add four tablespoons of seachem prime in this water and place the purigen for about 8 hours.
Step 7: Please take out the purigen from the container and wash it properly under running water to wash away all the accumulated residual chlorine.
Step 8: If the purigen is going to be used in a freshwater tank, it needs to go through another soak-in process for another 4 hours. Make the solution of the buffer in water. 2 tablespoons of buffer for one cup of water.
