For removing organic substances before they are broken down into ammonia thus putting less stress on the nitrifications cycle. It is exceptionally good on removal of Tannins producing extremely high water clarity like it was treated by a diatom filter.

Since this product is a macro-porous synthetic polymer and not functional (no ion exchange) it can be cleaned by putting the product in one liter of water with one full cup of salt. You will see depending on how long you use the product how dark the water will be. After that rinse, add the polymer and then add 1 part bleach to seven parts of water to achieve the white amber color back on the polymer.
