Ebay search for dechloranator crystals or pond dechlorantor. I also have a few threads in the set-up section about them. What you are buying is the main chemical that is in every dechlor made. You can get in a dry form and mix it with water to make a batch of dechlorantor for your tanks. The last i bought was 15 bucks and would treat about 75,ooo gallons when mixed.----------if you need help finding it pm me.
