Liquid BioOne from One Biotechnology is a natural drainline, septic and grease trap maintainer. Applied on a regular basis after a drain or septic treatment, it is designed to help maintain free-flowing drains, eliminate odors and reduce the number of backups between scheduled pumpings. It doesn’t contain enzymes or caustic agents and is safe for people, pets and pipes. It displays the U.S. EPA’s Safer Choice Program logo. Adding beneficial microbes after treatment on a regular basis can help avoid potentially expensive wastewater surcharges and fines. 941/951-4246; www.onebiotechnology.com.
