i run with 2 303 fluvals. i'm reading that carbon isn't the greatest thing for your filters because it holds back vitamins and nutrients your fish need. if this is true then what would you use to replace it. all i run in my filters is carbon, ceramik beads and foam filters. stopped using ammonia bags a few months ago and considering throwing those back in. i used to put peat moss in yrs ago and was told this lowered my ph. what do other people do with there canisters. just curious.

I run nothing but bio rings in my filters. No carbon necessary. I think carbon is a good thing for people starting out to help keep really nasty stuff in check, but if you're an aquarist into keeping O's and even more exotic fishes you will quickly realize that removing carbon to treat illnesses or what have you is more trouble than it's worth and the benefits aren't that great.

The only time i would use carbon is to remove medications. There is lots of debate out there suggesting long-term use of carbon can be very bad especially if not used and maintained properly.

No carbon for any fish IMO.

well i always used it but i would wash it out till the water was clear and when i cleaned my filters i would wash it out and every second cleaning i replaced it but i like the idea of not using it for the expense and the hassle of removing it for medications so thats what i will do. bio rings do they need replacing after time or not.

Nope, just rinse them in tank water every once in a while to remove any trapped debris. Remember the colonies of BB are living on there so you don't want to wash them away.

Carbon is a bitch when it has absorbers its fill of chemicals after it cant absorbs any-more it starts leeching them back into the water.

Also did not know it till recently:

Because of this, you don't really want to add a large amount of carbon at once. To a system that hasn't had it on before, you will want to start out with us very small amounts. For example for a 29 gallon system, startout with a few tablespoons in a low flow at area and then gradually increase that over time to a regular amount. Typically you should change the bag of carbon every 30 days.

It's really hard to monitor how quickly carbon is used up. Some studies indicate that with carbon left too long in the sump, you can start giving off giving back some of the pollutants that it has taken up so that's why this is important to remember. You don't want to just leave it in there for months and months and months at a time. You can actually be read polluting your system if you do that.
