I'm trying to locate a manganese cartridge for a 20" " Big Blue " water filter, with negative result so far. Any suggestions ?

Nobody on this forum uses a filter like this and know where to buy a manganese cartridge for it ?

I can get carbon block, resin and sediment cartridges but can't find manganese or green sand.

I just came back from a supplier that has all the supplies. Manganese, activated carbon, filter bags etc.

It looked like they also have cartridges but i am not sure.

The website is a little 'girlie' and unprofessional, but part of their business is water treatment consultancy and the guy (Khun Pitak) i spoke to seems very knowledgeably and his English was good enough to communicate and discuss what was needed.

Best to call them and ask them directly what you need because the website is really not good and does not even show 10% of what they have.

Just called them up, and they informed me that they don't have the cartridge with Manganese.

So further suggestions are welcomed.
