Like most things in our hobby, it’s not really an exact science. I run about 50 cc that I change every week on my 200L tank, and because I use an ozone reactor on it, I’m using about 800 cc on my 800 L tank that gets changed every few months. I noticed that they tend to be a dominant carpet anemone and the other ones start to wilt a little bit and then I replace it and the carpet and they perk back up. This is also been noticed by other experienced carpet anemone keepers here. For what it’s worth, are used to seachem matrix carbon.Thank you Martin, I am curious as I never know how much to use but on my 130.4 Waterbox how much carbon should I run? Thank you
