    You want your RV to be versatile. The beauty of RV travel is you have the convenience of hooking up your RV at your favorite campground or park, but also “roughing it” and relying on the RV itself to do the work. But nothing can ruin a dry-camp like having to deal with toilet odors or, worse, clogs and backups in your holding tank. You need something that is going to do that work for you, so you can focus more on what you got the RV for in the first place, relaxation, exploration, and travel with family and friends.

    Unique RV Digest-It’s powerful probiotic blend goes to work, quickly digesting solid waste and residual sludge build-up inside your holding tanks, preventing backups and clogs from happening in the first place. It’s advanced blend of bacteria and enzymes work quickly to remove the odor-creating pathogens from your holding tanks, replacing them with odorless aerobic bacteria, so your holding tanks can remain odor free.

Rick helped me at the time of purchasing your product, by advising me to use 600ml of treatment for my 400 litre black water tank for the first time, then 300 ml after. Thus I used 300 ml for out 200 litre grey water tank, and 150 thereafter. To my consternation, at the time of our first grey water dump, the first amount came out black, very smelly. The fluid cleared after a while. I then ran fresh water into the tank and added 150 ml. We dumped again three days later, and again the water flowed black then cleared. No smell this time. We are very water poor here in Australia and can't access Greta amounts to continually flush the tanks. A British video watched since, has claimed that the black is an algae growth caused by the additive...in this case RV digest. Thus we should reduce the amount added. Is this true? Or is there some other factor I need to get on top if. I really need to understand what is going wrong and I'm so far away, it is difficult to just ring you. Please help. Kathy

So far great stuff

I am new to this RV Digest-It liquid treatment. For the past 20+ years, I have used what the toilet manufacturer suggested. I am on my second 32 oz. bottle and am impressed. It took a few times emptying and flushing the tank to get rid of the old chemicals so that the bacteria could do its job. It didn't make the sensors work again but, they didn't work when I bought the RV. I am impressed with the lack of odor and I am sure that the owner of the park where I am now staying appreciates me not using a chemical-based product.

Unique Camping + Marine

Hal, thanks for giving RV Digest-It a try, and thanks for your 5-star review. We're happy to hear you've discovered the wonders of those powerful bacteria! Safe, odor-free, and effective; what more could you ask for? Stay safe out there, and do let us know if you have any questions.
