Recharging Purigen

Since my filter is out of commission anyway, and it's about time for me to recharge my bag of Purigen, I figure I might as well.

Couple questions:
1. I know it says 1:1 bleach:water solution. However, is there a rule in terms of how much total volume the solution should be in relation to the volume a Purigen one is reacharging (I assume so, but I can't find out exactly what that would be). I only have 100mL of the stuff in my filter, and I have it in a 1.5cup bleach/1.5cup water solution. Is that enough?

2. The instructions say to soak the stuff in a pH buffer after the 8hrs in the dechlorinator. Is there a way around this step? E.g. let it sit in a fresh water solution or something for another X number of hours? I don't have a buffer on hand and don't have a way to get to a pet store in the next week or so.

thanks :)
 
1. Yes, I think this will work just fine.

2. According to the directions the pH buffer is supposed to knock the pH of the Purigen back down to neutral because its pH will be very high after the bleach bath. I think if you put the bleached Purigen in a bowl with plenty of tap water and changed out the water every few hours until it's able to keep a neutral pH you could probably get around using the pH buffer. This is just a guess.
 
Some ideas

1. In my experience, 4 ounces of bleach and 4 ounces of water are sufficient. (Every once in a while I have to do a second bleaching.)

2. Seachem has changed its instructions so that you no longer need to to use a buffer soak. This is quite recent. Take a look at the instructions posted at www.seachem.com.
 
I just ordered Purigen a few days ago. Does it work well? How often does it need to be recharged? I know SeaChem's site states 6 months. Is this true?
 
I've heard nothing but rave reviews about the stuff. To be honest, I don't know exactly what it was doing. I got it to help with some water clarity/quality issues I was having a while back, but I charged several things at once so I can't say that if it helped immensely, just a little bit, or at all. I will say the issues I was having are gone, so take that as you will. :D
 
It sounds like really good stuff. I have pretty clear water, but I want it crystal clear along with lowering my nitrates with this. I am planning on using it with my carbon media in seperate cartridges.
 
Purigen is the best chemical filter ever invented. It does the job 1000% better than activated charcoal. I put some Purigen in October in my Eheims and it's still white.

Nothing beats the Purigen + UV sterilizer combo when it comes to crystal clear water. Purigen alone makes water look like liquid air.

You don't need to add a buffer and when Purigen is regenerated, it'll be back to the original color. So, you can easily tell.
