Hi, I just read on here under another topic that "several of us here do not run carbon of any sort in our filters"
My question is, why is this?
When I bought my external canister filter recently the lady at the pet shop made me buy a large bag of carbon & a net bag to put it in because she said it was absolutely essential,
I've only had my tank up & running for about 4months
So am I using it & replacing it monthly for no reason?
In the filter there is a black coarse spongy thing & a blue spongy thing and a piece of white fluffy stuff & in the next basket was just these ceramic noodle things & that is where she said to put the bag of carbon.
