Hello all .. I have until recently been changing the filter on my penguin bio-wheel every 4 weeks , after reading through various threads i have noticed that carbon is not a necessity , but I recently obtained about 4 pounds of the stuff , i now cut the top of the filter after the carbon has run its course and just use the filter itself , I was wondering if the carbon is beneficial in any way in other that removing meds . I have so much of it now i was thinking of changing it every other week ( if there is any point ) . Also if it is beneficial is there any way to incorporate it into the powerhead that runs my UGF
Thanx
Thanx
