Thank you! I'll get some tomorrow!

Filter charcoal, activated carbon, can be gotten at the fish store, or call
one of the water treatment companies. They use it to remove bad tastes from
the water. I put several pounds of it in the leg of panty hose and drape it
across the spill way of the water fall/ stream/ or filter return. At the
fish store the price will be a little high, but if that is what it is, it
will be worth it.
