Eh, carbon. lol

Carbon doesn't do much. Actaully, the only hting I find it useful for is removing meds. Other than that, it doesn't do much. And it becomes inactive after a week or 2. I actually take the carbon out of all my filter pads and save it, in case I need it later to remove meds. But on a day-tp-day basis, I have no need for it.

Not much reason to change the filter cartrige, either. That's where the bacteria live, no need to throw them out every couple weeks. Just a rinse in some old tank water during a water change should be fine. Then again, canister filters might require more maintainence than I am used to.

I agree carbon is a watse of time. While it does remove meds and other toxins its primary function is to deliver a slight improvment in clarity of water. This is nothing good tank maintinence won't deliver.
I have always been told to never include carbon in a canister filter as since it collects toxins they will be "spewed" (along with any meds) back into the tank once the carbon becomes inactive. I am not sure how true this is as I've always feared carbon in canister filters for this reason!?!?

I have several canister filters running as most my fish are big "tank busters" or jumpers and it is best to keep my water levels a bit low. And this rules out over flow filters unfortunately.

Carbon will become inactive well before your 3 monthly rinsing of your canister filter. Only ever rinse your filter in that tanks' water and try and clear out your hoses at this time to reduce resistance. This is all to keep the water flowing easily so the motor does not work too hard.

I agree, my fluval external canister filter had two baskets of carbon, i took the carbon out and replaced it with ceramic rings.

I think carbon is a good filtering media. I am using carbon and most amazing thing is it adsorbs most of the toxin in water. It also removes chlorine from water. Thus i dont need to add any decholorinator. You should change carbon every 2.5 weeks for best result.

Thanks, southern creature, I knew there was something I was forgetting! Clear water. Draftewood and some other things add tannins, which can lower pH, soften water, and often darkens the water. Some people don't like the dark water, but I have a "Amazon theme" tank, and so the dark water is much more like their natural environment. So I want to keep the tannins, so I get rid of the carbon so it won't remove them.

Replacing the carbon with ceramic rings is good, it gives more space for bacteria to grow. Unfortunately, my filter's replacemnt pads only come with carbon, so I have too cut a slit in them and remove it.

I was not aware that activated carbon will remove chlorine (and chloramine?) from aquarium water. Where did you learn about it? Maybe it was written on the box, and maybe i should buy some just for general purposes.

Man! Just try out. An the result you can see by yours that activated carbon will remove chlorine. I am using it.

I think if you want to use carbon, then it is perhaps best not in the canister filter unless you are dilligent enough to replace it every couple of weeks. Ths is easier these days as most start themselves flowing readily. Mine are old and difficult by comparison and this would cause things to get a bit wet around here unecesarialy.

I have a spare penguine bio-wheel l10 that can be use to mop up meds/toxins.

He is saying it's best not to use carbon in a canister filter unless you are willing to change it frequently. I am assuming he is not willing to change it frequently because its a hasle with his filter because his filter has to be manually restarted, but yours might be easier and start automatically, so you might be more willing to change carbon more often.

You could remove the fiber sleeve and fill it with something like ceramic rings if you would prefer.

Thanks KristinAnn, that's exactly what I was saying!

I'll try and be clearer in future mate!

Also if you want to use csrbon you could add a second filter to the tank for the 2week period that the carbon will be active for...say an over-flow/bio-wheel type of filter. I think this is much easier to do as you would not have to touch your canister filter.

I have left carbon in for months at a time when I first got into the hobby and I don't think there were problems, but I never tested anything back then. I'm not sure if carbon is harmless or bad once deactivated. Some people say harmless, others asay it re-releases all the toxins. You should be able to get ceramic rings at the LFS.

I have heard biowheels aren't all they are cracked up to be, but I don't have any experience with them myself.

I agree that the bio-wheel (aerobic bacteria) part is not nearly what it is claimed to be.

It is just an easier system to slot filter cartrages in and out of
A basic over-flow filter is just as good for this.

I got the bio-wheel from a sale bin (I think that says a lot) and often the wheel won't turn. But it's a good over-flow filter.

Carbon does not remove Chlorine or Chloramines in any way. It does more than just remove meds & colors however. It removes many other organics. Helps the water smell much better because of it.

It can sometimes leech phosphates back in the water after it is dormant, but as long as you change it every month, it won't be an issue. If your tank is ridiculously overcrowded, divide it by how many time you would reduce your fish load if had any sense.

It is perfect for use in canisters, probably more so than any other type of filter.

That being said, there are many superior resins that can also be used. Polyfilters, Purigen, Chemipure, etc. that last much longer than a month.

Carbon, or some other absorbent resin, is an important part of any filtration system.
