OMG Aquatics Posted March 14, 2015 Report Share Posted March 14, 2015 Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach). Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime®, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoon of buffer per cup of water (Discus Buffer®, Neutral Regulator®). Am I required to do this step or is it optional? For freshwater use, soak for 4 hours with a solution containing 2 tablespoon of buffer per cup of water (Discus Buffer®, Neutral Regulator®).

Shrimpy Daddy Posted March 14, 2015 Report Share Posted March 14, 2015 Just soak with Prime and don't need to use Discus Buffer. The final step will be rinse with RO or filter water to remove any left over tap water residual. OMG Aquatics 1 Quote Link to comment Share on other sites More sharing options...
Shrimple minded Posted March 15, 2015 Report Share Posted March 15, 2015 If I'm using two purigen bags and swapping them out, what is the best way to store the recharged purigen when it is not in use? I double ziploc-bagged mine with some water with a heavy dose of prime and placed it in the refrigerator, but it seems to have discolored to a medium shade of grey. Should I re-soak in prime and rinse prior to use, or do you think I should just discard because of the aforementioned discoloration? Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted March 15, 2015 Report Share Posted March 15, 2015 If it turns medium grey, it means you soak in Prime too long. Shrimple minded 1 Quote Link to comment Share on other sites More sharing options...

Shrimpy Daddy Posted March 15, 2015 Report Share Posted March 15, 2015 You are welcome. When soaking with Prime, remove it once your Purigen turns white, but at least 2 hours. To ensure it is totally dechlorinated, after rinse, bring it close to nose and smell. If no chlorine smell, then it is done. Also store the Purigen in fridge with moist state and not filled with water. Too much water will cause bacteria to grow. Quote Link to comment Share on other sites More sharing options...
Ch3fb0yrdee Posted March 15, 2015 Report Share Posted March 15, 2015 Can anyone tell which is the new and which is the purigen whose been recharged at least 5x? Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted March 15, 2015 Report Share Posted March 15, 2015 The left one is recharged and the right one is new but exposed to air (maybe bad packaging) for too long. Quote Link to comment Share on other sites More sharing options...
Dendrobatez Posted March 15, 2015 Report Share Posted March 15, 2015 What could cause it to go bad? I had a new 100g bag used for 2 weeks, soaked in 1:1 bleach and then the recommended amount of prime/water for 5 hours and when I took it out of the mixture it was dark brownish Gray and smelled rotten. I've recharged purigen from my other aquariums about 30 times in the past year and this was the only time it ever happened Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted March 15, 2015 Report Share Posted March 15, 2015 Smell rotten is due to the sulphur in Prime. Turns brown after prime is not normal. If it turns brown after soak prime, you could claim warranty. Quote Link to comment Share on other sites More sharing options...
julianzh Posted March 21, 2015 Report Share Posted March 21, 2015 The recharge process scared me a lot. Rather buy the 500ml on Amazon. Much better and cheaper. Quote Link to comment Share on other sites More sharing options...
RyeGuy411 Posted March 23, 2015 Report Share Posted March 23, 2015 I have recharged many times, if you follow the instructions properly there is nothing to worry about. Dendrobatez 1 Quote Link to comment Share on other sites More sharing options...
