Just, hopefully, a quick question. I was after some Purigen, not the liquid form and was wondering where in Perth I could track some down.

Thanks in advance

I know for sure that Malaga & Veba's stock it, not sure of the other PCS Sponsors .

Midland have 30% off all Seachem products. Would be worth giving them a ring too.

Thanks for the free plug, But we dont have any Purigen in.
We are no longer stocking Seachem products hence the 30% off.

I have found the API Bio Chem Zorb Works very well, and it can be recharged using water and API Aquarium Salt.
Unlike Purigen that has be recharged in chlorine bleach.

Bio-chem Zorb cannot be re-charged at all, you are meant to replace the pouches every 3-6 months.

NitraZorb on the other hand can be re-charged in salt water (it does generate some heat but this is normal) but this is completley different to bio-chem and will not remove dis-colouration or odours.

Bio-Chem contains two ion-exchange resins and a high porosity activated carbon but has never been marketed as a rechargable product.

Actually Bio-chem Zorb can be "recharged", or at least the ion-exchange components can, but the technique will be beyond most people, and in all probability the cost in time and chemicals will make the effort not worthwhile.

It should be noted that Purigen and Hypersorb are NOT ion exchange materials, but are classified as macroreticular adsorbents. The function of bleach is to "burn-out" or oxidise adsorbed organic compounds, and by changing some ionic characteristics of inorganic compounds, to assist in their elution; though the propensity of the resins to adsorb significant quantities of inorganics is limited.

I sent you a pm regarding some Purigen you might be interested in.
I have found the stuff to work wonders....within 24 hours the fish look like they are floating in air.
The 'recharge' process is relatively straight forward too.

hey guys i put BIO CHEM ZORB in my filter this morning which is supposed to be the same. it is 30$ to treat 200L tank for 3-6 months and is recharged by putting in saltwater for 48 hours ( easy for me as i can use a bucket of old water from a water change on my marine). already in 12 hours its made a noticable difference.. will keep updating my experience with this product. its an alternative thought anyway since the conversation moved to alternatives to purigen. i actually asked for purigen and the store owner told me not to bother.. this is better and better value.

I know it says in the instructions that it cant be recharged, But I have used the same mix for Nitra Zorb, and it seemed to "recharge it"

[Mr_docfish]

True, as Syd said, the ion exchange part of the Chem zorb can be recharged, but the other resins and carbon will not be recharged using salt. Purigen can be recharged only several times, but will gradually be less useful....

Purigen in my opinion (after talking to Syd about this and similar products) is the more superior product, but value for money in the long term and ease of use... well that is very debatable.
The most important consideration is what you need the products for, and can you find a better method for the long term to achieve the same result, such as a more efficient filter, better quality food and more adequate/frequent water changes or just less fish. In general, if you use one of these products and you notice the health of the fish improves, then there is something wrong with the current system of general fishkeeping in that tank. These products can be relied upon for short term problems (new tank, over crowded fry raising tank, post medication, lack of time due to holidays/job requirements, unexplained problems etc) but should not be needed in the long term if proper management skills are employed.

[FishGal]

Wow you ask one simple question and get all these replies! Thank you all so much, you've answered questions I didn't even ask but in the process informed me about some other important things in the decision making process!

[Boof86]

hehe he oliver you got a good point except the biggest appeal about it to me is its ability to remove tannins:P you gave no alternative... carbon pads did nothing for my tank ><

[Mr_docfish]

Carbon in pads are the poorest (value for money wise) form of carbon you can get (not very well sealed, and the amount of carbon available is minimal, only several grams at most per sheet)
Activated carbon in granular and extruded form is far superior and more value for money.... and it is also good for the garden/flower pots when you finished with it.
