Blue Pond!
 

We accidentaly bought Crystal Blue and place it in our pond that is 12 by 13 with approximately 3,000 gallons. The pond is one month old and we have 6 small koi. We put in active carbon but after 24 hours it hasn't changed the color.

Should we drain 25% of the pond and replace it with water? If I do this, I probably need to put some dechlorinator. Is there any suggestion because I hate the "Smurf" blue.
