Carbon Filter necessary?
Hey guys just a quick question.
Im about to buy some filter products for my AC 30 and my AC 70, and I was wondering if I really need to buy the cabon packs. My tanks have been up and running for over a year, and im pretty sure there is enough bacteria to help with the filtering.
Can I just use a sponge, more Bio media, and then filterfloss maybe?
O and what to know your guys opinions on what kind of combo works for you too.
