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.

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.

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

Oh my someone told me once a week! PM me if this is too much...

Carbon is one of those things that just need re-charging! If you wanna make it last and save some money....clean it and then run it under REALLY cold water! This will recharge the Carbon thus leaving more money in your pocket for your hobby! I change mine every 6 months and seems to be working good for me!
