It's just not needed, just an unnecessary additional cost.
Agree w/ above. Unless you're trying to rid the tank of meds or tannin discoloration, you'll be fine w/out it. Once carbon becomes 'exhausted' (5/7 days) it actually begins to slowly leech the impurities back into the water!! Mfgrs. suggest replacing the carbon often cause it keeps you spending money w/ them. If you insist on using it & want it to be effective then you gotta keep buying more. I would save some carbon for emergencies & use the extra space for 'bio'. JMHO Good Luck
milkman407: If you're a carbon fan I still luv ya & so do the carbon mfgrs.. The truth is you can get rid of the fishy smell w/out using carbon. Increased w/c combined w/ increased bio will have your tank 'cheery' in no time. Haven't used carbon except for med removal in years. No smell what so ever. The 'BOSS' (my better half) who doesn't share my passion for aquaria, would be the first one up in arms. She's a country girl & as she puts it "can smell a hummingbird fart a mile away". moneygetter1;495624; said:Agree w/ above.
