I think I may experiment with the Orchiata "Precision" grade - even finer than their "Classic"
Thanks.I have another query. Here in Ireland, it is quite hard to get horticultural charcoal. You would have to get it fron england and shipping charges would make it quite expensive. Would a mix without the charcoal be okay?
Personally, I'd avoid it. Those grades are "activated", meaning they have been heat treated in a manner that increases the mircroporosity to an extreme degree so that it will adsorb like crazy.What about using aquarium/fish charcoal instead?
yes, it mostly works as a filter and air space maker.Thanks.I have another query. Here in Ireland, it is quite hard to get horticultural charcoal. You would have to get it fron england and shipping charges would make it quite expensive. Would a mix without the charcoal be okay?
Good if you change every year, otherwise see Ray's post.What about using aquarium/fish charcoal instead?
