	adding tank tanins
koi keeper Moderator Posts: 3203 Kudos: 2033 Votes: 240 Registered: 29-Dec-2001	I am adding tanins to a south american tank the easy way; with dead wood. Thought the pictures were kinda neat. Koi Koi Keeper attached this image: Empty chairs at empty tables, the room silent, forlorn.

Once added into a water source they effectively replace hardness chemicals such as Ca. This softens the water and provides blackwater fish with the water parameters needed for them to prosper.

If you have a little, it will be a light tea color.

The only sure way of obtaining a working "dosage-administered" source of tannic acid is to make your own via boiling various organic materials; a smelly and drudging process.
