Carbon Filter Refill

[TommyT]

Thanks guys handy info and the trick of washing and baking it sounds useful, I’m just thinking having a bag of refill charcoal would be handy in case my filter stopped at some point, so I can relatively quickly refill it, also saves on paying for a whole new filter

I keep an extra amount so that I can refill the filter and then wash the used batch. You can usually find the pelletized activated charcoal at the pet supply stores. That's where I bought mine.

[IMO]

Thanks @TommyT il most likely do that

So looking at size 4mm being the right size I think it said, are these OK? https://www.ebay.co.uk/itm/264600719258

Those should work fine.
