Regenerating my purigen (pics included)

  • We are currently upgrading MFK. thanks! -neo
The seachem website has instructions and if you look under the questions section for purigen they answer the reason for the different buffers wheather you need it or not.
 
About the 1:1, that means 1 cup/quart/etc of bleach. to 1 cup/quart/etc of water.

I read the site, they explain why you should use a acidic buffer (Anyone know the PH of bleach Edit: 12.6? That's about the PH of the purigen when you're done with recharging.)

Q: I recently just regenerated the Purigen product. In the end, I used your neutral buffering product for the final process rather than the Discus or acid bufferer like suggested. It was under my rational that the reason we use the buffer was that the regeneratory process basically renders the product as at one extreme end of the PH scale. We are basically just preventing it from affecting our overall PH by buffering it. Since I strive to keep my aquarium at a PH of 7.0 was this a correct action on my behalf ?
A: This was a correct assumption and I do not see a problem with your action. As a precaution, I would test it in a cup of water (preferably RO or DI). If putting the fully regenerated product in DI water results in the pH of the DI water rising above 8.0, I would reintroduce the resin to a solution of Neutral Regulator for a few hours.

Still curious if you can outgas the chlorine instead of using dechlor, I might give it a try as I have more then I need.
 
What about multiple rinses in a small tank with a power head.
If you place the recharged resin bag in a 10 litre container of clean water and run a power head for ten minutes then you reduce the contentration of chlorine from parts per litre to parts per ten litres. Repeat the cycle with fresh water, now you have parts per 100 litre, do it again and you parts per thousand litres, again and parts per ten thousand litres......at six times your down to a millionth of the original concentration. That should take an hour.
I imagine that residual chlorine in parts per million in the purigen will be of little concern if your using activated carbon to remove it.
Just thinking out loud here... Make sense?
 
Makes sense, too much thinking. I just rinse, drop in a capful of prime, wait a few hours, repeat, drop in tank with a a capful of Prime.
