Question:  Is there a biomedia for my aquaponics system that is safe for the fish?  I understand that certain plastic sheeting products off gas thus killing fish. Do you have a biomedia for this purpose?

Answer:  Enkamat 7010 is the answer for your biomedia need.  This product has been used in filtration systems for the past 15 years for both aquariums and aquaculture. It has been used in the commercial fish industry.  Enkamat stops bacteria from reentering the tank by providing a bed for bacteria to rest on.  The open weave offers a safe haven for fish eggs to rest until they are ready to hatch.  Enkamat 7010 has also been used as a filter for pond pumps.  Call Global Plastic Sheeting, and ask for Ken.
