Greater than one weekI purchased this product after purchasing many other holding tank treatments over the years and this one is the best by far. I have tried for years to clear the tanks so that my gauges would say 0% full after being dumped. At the most after using other products my tank gauge wouldnt read any less than 33% when they were completely empty. I emptied the gray and black tanks, mixed a scoop of this product with a gallon of water for each holding tank. I let it sit overnight and the next day I opened the tanks one by one, turned the flushing system on and watched thru the clear sewer elbow a huge pile of gunk pour out for a minute or so then nothing but clean water proceeded. I have never had the tanks clear that quickly. This stuff is amazing, I will be putting a scoop in after each dump for sure. Im so glad I took a chance because of the other fantastic reviews from other reviewers and I purchased the huge bucket. This product deserves a 10 if it was possible.

07-06-2025MORE THAN 7 YEARS AGO WHILE AT A RV SHOW I DECIDED TO TRY YET ANOTHER HOLDING TANK TREATMENT. FINALLY!!! A PRODUCT THAT WORKED AS WELL AS WAS PROMISED BY ITS SELLERS. THEY BECAME SELLERS OF THE PRODUCT AFTER USING IT THEMSELVES FOR A GREAT PERIOD OF TIME. BEST PART FOR ME WAS NO PERFUME ODOR AND FOR MY HUSBAND THE TOTAL DESTRUCTION OF BLACK WASTE. A WIN WIN!!!
