Bio-Tab from Century Chemical Corp. is a tablet that sinks to the bottom of a septic tank where buildup problems begin. Its time-release technology is designed to gradually dissolve to create a growing area of activity at the bottom of the tank. There, self-reproducing bacteria and enzymes quickly grow as they digest and liquefy the organic waste. The tablet establishes itself by working from the inside out. Regular usage — combined with routine pumping — can help maintain a septic system in good working condition while helping to keep the proper level of bacterial action established and reducing odors and gases, according to the maker. 800/348-3505; www.bio-tab.com.
