I'm a bit curious about this. So Brita water filters use carbon cartridges to filter out water impurities, including chlorine. Would carbon in an aquarium filter thus filter out excess chlorine too? Say you run out of water conditioner/dechlorinator and you can't get to the store to buy any but you need to do a water change. Would carbon filter out enough chlorine to make it fish-safe on a short-term basis?
Thoughts, opinions, scientific facts, anyone? (and yes, guess who just changed the cartridge in the Brita water pitcher, haha)
