I know that others are concerned like me about the chlorine and chloramines in their tap water during water changes. I also don't like the idea of just adding treatment to the tank and then adding the tap water. So, I was thinking, would it be possible to use one of those Mircle-Gro garden fertilizers for water changes. I am talking about the one that has the bottle attached where you put the fertilizer and then attach it to the hose. The water treatment could go in the bottle. Any thoughts, ideas?
