changing carbon
 

How often do you all change your carbon? I've been changing it out once a month, but having the three tanks I go through quite a bit of it. Since I've never noticed any yellowing of the water I'm thinking I can stretch the changes out some.

I change every month. If I skip a month I notice my old water in my WC bucket has a slight yellow tinge to it.

I change mine every 4-6 weeks. I don't really notice a difference either but I run it anyways :razz:

I change out at the beginning of every month

Once a month here.

I change mine out every 30 days giver or take a day.

Once a month. I'm using some really fine carbon in a phosban reactor so after 4-5 weeks its so plugged up that barely any water is travelling through and I'm forced to change it.

i haven't changed my carbon in my 12g nano since the day i bought it... now going on 2 years...lol heres a pic

Monthly (well, approximately) for me too. I think I notice the tank is brighter the day after a switch out which tells me I might be stretching it out a bit too long. :neutral:

I change about once a month, if I go longer the water does get a tint of yellow.
