Is there a difference in quality of charcoal. Saw some in LFS that seem to be cheaper than others. It apparently is from China but not sure whether the more 'branded ' ones come from China as well, just that the packaging is better.

There is. The more better grade charcoal absorb better and faster as well. Generally they are more fine and smaller in size to aid absorbing faster. The cheaper ones are usually bigger and least process. But well, both achieve the same result. Just in terms of absorbtion speed. And both need to be replace.
If i am not wrong it can be recharge in salt water solution
Can anyone confirm this last bit?

Activated carbon / charcoal cannot be recharged at home.
Most "normal people" just have no way to do this, unless you happen to be able to generate a 600 - 900 degree Celsius inert environment, which is the easiest method to reactivate carbon.
The reason some activated carbon is more expensive than others is because of the method used to activate it. Chemical activation is the cheaper production method, but will increase dissolved phosphates in your water(not a big deal in freshwater tanks.)
Marine aquarists use the more expensive pyrolitically activated carbon almost exclusively because excess phosphates in marine tanks lead to serious algae problems.

Wow, learnt something interesting today, thanks! So it's back to doing it the old fashion way, buy it!
