HOLDING TANK TREATMENT THIS IS A SOLUTION THAT REDUCES EMBARRASSING ODORS, ELIMINATES CAKE BUILD UP, TREATS ANY GREASE BUILDUP, ALONG WITH DEGRADING THE TOILET PAPER IN THE HOLDING TANKS. Although, drain lines and interceptors are not designed to be microbial reactors, they provide nutrient-rich environments for bacterial growth. But they need the right microbes to optimize biological treatment. Hydraulic retention time is limited and organisms with very high rates of activity are required. THE RIGHT MICROBES OR "PROMICROBIALS" MAKE HOLDING TANKS WORK MORE EFFECTIVELY. FEATURES: LIQUID & POWDER Easy to use formulation that can be applied manually. Stable, high count blend of promicrobials with a 2 year shelf life. Specifically targets a wide array of organics under varied conditions. Effective pH: 5.0- 9.8 (optimal 6.5- 8.5) Effective temperatures: 38 degrees F to 145 degrees F. Enzyme production: lipase, protease, amylase, and celluase. Contains aerobic and anaerobic (facultative) metabolic pathways. Bacteria count: over 500 BILLION PER GALLON (liquid) . Use in Marinars,RV's, Boats, Yachts & Motor homes.
