Fresh-Tank Pro Deodorizer

BIO GREEN ® Biodegrader 

Natural cleaner and deodorizer for RV & Marine Holding Tanks,               Drains, and Septic systems.


While traveling in our Airstream Trailer, in 1985, we stopped at a hardware store in Ramona, CA.  We noticed an all-natural product for drain cleaning and septic systems.  

With most RV Treatments at that time being formaldehyde based, we were very skeptical about the safety and potential harmful health effects of the few RV Holding Tank Products available. We knew other RV Users were also concerned about safety, and thought that that, maybe, this all-natural product could be a safe alternative. RV Parks would love it, too, as when patrons dumped their holding tanks, they would also be treating, rather than harming, the health of the park’s waste systems.

We contacted the manufacturer, who provided the Material Safety Data Sheet, Lab Reports, and other scientific documentation, confirming the safety and effectiveness of their product.  They told us that, in addition to drain cleaning and septic tank usage, it was used by major waste treatment facilities.  They felt that, although they had not marketed it into the RV & Marine Holding Tank Market, that their product would, indeed, also be effective for that use.

That began our journey into the RV Industry, and led to our Bio-Green Biodegrader Products, sold for use in RV & Marine Holding Tanks, Drains, and Septic Systems.  We have now been selling our products to satisfied customers, for many years.

"It is not often anyone can claim a septic treatment works while sending the payment but here it is!! On Sunday the 18th I used one container (4 oz.) of Bio-Green. I mixed it with about 3 gallons of Luke warm water and let it stand for 1 hour. I then poured it directly into my #1 and #2 “0” boxes. “0” box #1 is where I used my dip stick and is the first box from the tank. In the morning I can get a low reading before everyone gets up and a high reading late in the day. I will send you a more detailed report later but today I can tell you my high reading is where the low reading used to be! I am very pleased to get results I can see in just 3 days with no other changes or treatment". 

Thank you, Dennis L.
