Carbon, for how long?

[ben1]

For how long can I use carbon on my reef tank?

 

[shifty51008]

I run carbon 24/7 in my tank and change it out every month

I, too, run carbon 24/7, changed monthly or so. Been doing it that way since the mid 1980's with no ill effects yet

24/7 change out every 2 weeks.

 

[ben1]

why once a month?

1 month is just a good timeline because there is nothing you can test for that tells you it is exausted except for the water looking more dirty.
