i was reading the box of the carbon i got and it said "this will not raise ph levels if used properly"
does this mean there is a limit to the amount of carbon in the water. the reason i am askin is b/c i have a 90 gal tank and over filter it with 2 filters meant for 70 gal each. is it okay to put carbon media in both the filters?

Like the rest of these guys said, its not needed. I only use it to get meds out of the water. But then again, I've only had melafix in there anyway!!!
