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.

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.

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"

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.

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.
