So you do a water change and you use lets say, Big Als' water conditioner to clean the water and chlorine. every water change, you use it on the water you are adding to keep it clean. So now you have someone who does a water change and uses prime to remove the chlorine. Now ok, prime detoxifies nitrite and nitrate as well, but only for 24 hours, so it seems pointless. What the point of using it for that as it doesn't fix the problem just masks it for 24 hours. Therefore the only real use i see for it is to clean the chlorine out, which any aquarium chlorine remover does. So prime is twice as expensive as a no name aquarium water conditioner, an really adds nothing more than a water conditioner. so why spend the extra money. Basically...whats the point of it?
