Clean odorless water!
This is the best activated carbon I’ve ever used. My tropical fish love me.

Way overpriced
Used this to help clear the pine tannin from our pond. Took a few weeks to clear it up but it did help and the fish weren’t bothered. Way too expensive for what you get.

$20 price increase since last ordered, so researched and found much cheaper...
Lowered rating from 5 to 3 stars only because of big increase in the price since my last purchase and found much less expensive AC elsewhere. Purchased 5 pounds in June 2018 for total delivered price of $79.92. Checked today to see about reordering 5 pounds and the price is now $20.00 higher. This product did arrive in a box and not a tub. I used it several times having to very thoroughly wash it in the media bag each time. Lots of fine particles and dust in the product. Because of the large price increase and fact that this product needs a lot of washing before being used, I'm going to search for a more competitive price with another supplier and hopefully it will also contain less fines. Update: Just placed an order on eBay for 20 pounds of AC including two media bags for $32.54 delivered. Positive reviews on it and worth trying in my opinion. Happy this supplier jacked up the price now because I would have otherwise just reordered.Original review: Product worked great. Koi pond around 500 gallons and couldn't clear up brownish colored water from tannins. Nothing was working including 10-15% water changes. Read about using a few pounds of this in a media (mesh) bag to clear up the water. Added around 5 lbs and WASHED the media bag with the garden hose until no black was coming out of it. Then placed the media bag in my skimmer while temporarily removing the filter and later just moved it to where the pond water would run through it before going over one of the waterfalls. Could see the bottom of the pond and koi clearly by next morning. If using medicine to treat koi, be aware that activated carbon reportedly removes it from your pond.
