How much and where would I find activated charcoal?
Can anyone tell me about activated charcoal? I have heard it mentioned several times here on the forum to take the discoloration out of pond water but how much, how do you put it in the system and where is a source for it? I have a large pond so will I am sure will need quite a bit.
Thanks in advance.
