Alfagrog (aka Supra in USA)
Anyone heard of Alfagrog (aka Supra in US) and is it available in Spore?
Understand Alfagrog is a very porous inert ceramic filter medium. It is produced in England especially
for water purification as well as biomedia for bacteria growth in the koi poind filter chambers. It is unmatched for effectiveness and value for money.
