Of course you can, it's a risk involved in using it so one has to determine if the risk is worth the benefit. You can't say a tank has crashed from not using carbon, plan and simple. You can argue the use of carbon MAY prevent a crash but the lack off is certainly not a cause.

Salt is not optional and neither is water or the container everything is held in, those risks are unavoidable.
