RyeGuy411 Posted July 9, 2015 Report Share Posted July 9, 2015 Ive used purigen for a while and usually keep an extra bag in some RO water until I need to swap it out. One bag I forgot about recently and the container was bone dry, is the purigen ok or should I get a new bag?

Faralon Posted July 9, 2015 Report Share Posted July 9, 2015 Its fine. When you get it, its all dried up, and you can apparently reactivate a used bag with bleach. (and obvious rinsing / chlorine removal) If it can withstand bleach, it'll be ok if it dried out on ya. I have a dry bag here waiting on reactivation.

RyeGuy411 Posted July 9, 2015 Author Report Share Posted July 9, 2015 Its actually packaged damp like a sponge. Quote Link to comment Share on other sites More sharing options...
Faralon Posted July 9, 2015 Report Share Posted July 9, 2015 The new packaging, in the tear off bag, is different. When it was packaged in the cardboard, or if you buy it in the plastic bottles, its dry. Guessing they pre-rinse it in the tear off bags? Original instructions said to rinse it 1st.

Faralon Posted July 9, 2015 Report Share Posted July 9, 2015 So packaging aside, it looks like it might be bad to let it dry out once it has been used. I found this on the Seachem website. "You are correct that the Purigen that is packaged in the plastic bottle is damp, and that the pre-bagged is usually dry. This is normal due to the difference in packaging and it is not an issue. The problem arises when you have placed the Purigen in use in a filter then remove it and let it dry out. If you remove the Purigen from your filter you should store it in clean fresh water in a sealed container." They done explain further if a dried out bag becomes unusable. My "guess" that it'll still work, but not be as effective and/or, drying it will crack/shrink and already used bag creating more dust. Its a polymer resin, nothing organic about it, so it should be fine to reuse. Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
JamesHe Posted July 9, 2015 Report Share Posted July 9, 2015 I normally store my backup bag in complete dry condition. RyeGuy411 1 Quote Link to comment Share on other sites More sharing options...
shrimpfreak Posted July 9, 2015 Report Share Posted July 9, 2015 Couldn't you just use it and test your water over time and see if it is working? Quote Link to comment Share on other sites More sharing options...
Shrimpscales Posted July 9, 2015 Report Share Posted July 9, 2015 I have always kept mine moist in a plastic bag. Just the other day I went to use it and found mold growing on it. Of course I had to start the whole bleaching process over again. One thing I don't understand is why you have to soak in the buffer solution. That buffer is kind of expensive and at one tbs per cup you can use a lot. Quote Link to comment Share on other sites More sharing options...
Faralon Posted July 9, 2015 Report Share Posted July 9, 2015 Buffer is due to the high pH left after bleaching. It's described here, as well as them verifying that dry purigen might make the beads crack and create more dust. Let the purigen soak in some water for a few days after regenerating and rinsing. If it's not throwing the pH thru the roof, save some $$ on the buffer. http://www.seachem.com/support/forums/archive/index.php/t-199.html Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
8062282 Posted July 11, 2015 Report Share Posted July 11, 2015 I tried sitting some purigen in a pot with hydrogen peroxide as an experiment. Seemed to work as the purigen is now as clean as the new stuff. Safer than bleach as well -- Stay Happy Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted July 11, 2015 Report Share Posted July 11, 2015 Now THAT is a totally brilliant idea! 8062282 1 Quote Link to comment Share on other sites More sharing options...
ElevateShrimp Posted August 8, 2015 Report Share Posted August 8, 2015 the hydrogen peroxide will not clean the purigen properly though, those ion exchange resins are very porous. I would only trust chlorine ion to remove the organics. Using bleach is quite safe in the aquarium hobby, because the chlorine ions are very unstable they will leave the solution as chlorine gas over a period of about 2 days. If you use hot/warm water with your bleach 50/50 solution, the chlorine will be mostly gone by the next day. From there you wash everything after waiting about a day or if ALL of the purigen is white. I usually will resoak the washed & renewed purigen in more hot water, then I will replace that water with fresh tap water with 4x concentration of Prime and let sit for 8 hrs+.
