cichlid fiend;3894650; said:Carbon helps out with the water parameters, like removing odors, discoloration, and ammonia. SO please tell me how its useless. ITs made to keep ur water crispy. Im not saying if u dont have it, ur water wont be crispy. BUT it will definitely HELP!!! Specially if you have a life and u cant do a WC everyday or for that matter every week.
CARBON HELPS OUT,POINT BLANK!!!
Yes, it does absorb ammonia, but if your tank is cycled and you aren't overstocked and/or you don't overfeed your fish, the beneficial bacteria should remove all the ammonia created by converting it to nitrite and nitrate, so this shoudn't really be necessary. If your tank is cycling, you want to allow a small amount of ammonia to be present - if it's not there for the bacteria to use, you won't build up enough of a bacterial population to handle the wastes your fish will produce.
As far as the carbon, it adsorbs a number of chemicals, including some that are good as well as bad. The major reason for using it is to remove medications that are used in the tank. It will also remove small amounts of dyes, discoloration from tannins leached from wood, and some odors. It's used in some specialized tanks for removing toxins produced by corals (also some fish species) in saltwater tanks. It can also remove some harmful metals in you tapwater (if these exist).
It's not necessary to use carbon on a daily basis, unless there's a specific reason you have for doing so (lessen water discoloration from driftwood, removal of metals from tapwater, etc.). In most cases, regular water changes will do just as much if not more to benefit your water quality. It's still good to keep some onhand, however, for emergencies (someone sprays a chemical in the room and some accidently gets in the tank).
...... doesn't sound useless , just a waste of money and a waste of time.....
Did you know it becomes toxic and aneriobic after 2weeks and begins poisining your tank?
