Good one

Good

Work great in my fish sump tank

Se sumergió hasta que saliera el aire y se colocó cerca de la bomba para que pasará el agua por el mismo, muy funcional!

Works very well. Was very effective at almost completely removing the garbage smell from my garage (we have to keep our garbage bin in the garage). The size of each piece of charcoal is very good (small pebble size), and there's not too much fine powder. What I did was fill a few women's stockings with the charcoal (about 6 inches in length), tie up the end, and then let it sit in the garage. Four such stockings worth was enough to do the trick... perhaps less would have also sufficed. If I wanted to make them even more effective, I could hang them on the inside of the garbage bin (by sticking a hook to the inside wall, for example). To fill those 4 stockings, I used about 2/3 of the container. I was expecting it to last longer, but I guess it's not too bad, since hopefully those 4 stockings will be effective for quite a while.
