I'm shopping for activated carbon to remove tannins from my pond. The best price I found was about $2.50/lb including shipping on ebay. Anyone know who might sell it cheaper?
I don't want to invest in it unless you members recommend it for clarifying the water.
How much do I need to treat a 5,000/gal pond? How often will I need to change it out during the season?
How long will it take to remove the tannins? I plan to do a partial water change while I do the major cleanout this spring and then treat with the carbon. I can't do a total water change because I don't have a holding tank large enough for all my Shubunkins.
