Re: Water Changing
The following is the absorption potential of various substances by activated carbon. As you may or may not know, carbon is used much more than in the aquarium. The list goes on, I am just putting down what I feel is most strongly removed, at an efficient rate:
Arsenic, bleach, chloramine, chlorine, chromium, colors, dyes, gold, insecticide, odors, monochloramine, tin, acetic acid, cobalt, detergent, hydrogen sulfide, mercury, ozone, potassium, silver, soap, solvents, vinegar.
Things such as ammonia, nitrates, hardness, and alkalinity are virtually impossible to eliminate with carbon, at least in measurable amounts.
