1. Happy Campers Organic RV Holding Tank Treatment

  • Best Overall Product

The Happy Campers Organic RV Holding Tank Treatment is one of the industry’s most reliable organic treatments.

Traditional black tank treatments often utilize harsh chemicals to break down waste and shield septic smells, but this new organic option does the same job without harmful synthetic materials.

This treatment is entirely biodegradable, which makes it a great choice for environmentally-conscious consumers.

While this is an excellent product for those who want to avoid harsh chemicals, it’s also extremely functional. The Happy Campers Organic RV Holding Tank Treatment does an excellent job of masking septic smells and customers are delighted with the power of this organic treatment.

If you want to enjoy your next RV trip without sewage odors, it’s hard to find a more robust black tank treatment.

Another feature to consider is the product’s ability to work in both hot and cold temperatures. If you’re someone who uses your RV at different times of the year, it’s essential to choose a treatment that can handle winter and summer temperatures.

The manufacturer recommends that you fill your toilet with a gallon of water, input a single scoop of treatment, and flush the toilet to use this treatment.

You should repeat this step a second time for the best results. If you use the treatment correctly, it should break down most solids—it’s even effective at breaking down standard tissue paper.

We’ve ranked this as our best RV black tank treatment because it combines value with performance and biodegradability.

If you’re looking for an affordable product that eliminates odors, it’s hard to go wrong with the Happy Campers Organic RV Holding Tank Treatment. Its ability to function at extreme temperatures also makes it a useful product.

RV Black Tank Treatment Buying Guide

Now that you’ve looked at the best black tank treatments available on the market, it’s time to decide which product is most suitable for you. We’ve created a comprehensive buying guide to educate you before you buy your next RV black tank treatment.

Features to Consider When Choosing the Best RV Black Tank Treatment

There are a few essential features to consider before purchasing if you’re aiming to find the best RV black tank treatment for your preferences. Let’s explore each of these features in more detail below.

Cost

The first feature to consider is cost. If you can’t afford an RV black tank treatment, there’s no point considering it as one of your options. Fortunately, there are plenty of excellent treatments available at affordable prices.

As a rule of thumb, if you’re willing to purchase a large number of treatments at once, you can save money on the “per treatment” cost.

Effectiveness               

Next, consider how effective the treatment is at masking odors and breaking down wastewater. If you want to enjoy your next road trip, it’s essential to invest in a treatment that can keep your RV comfortable.

It’s also a good idea to consider how long the treatment lasts—the best products on the market last at least seven days.

Type of Treatment

With so many types of treatments to choose from, it’s essential to consider which one is right for you. If you want an easy-to-use capsule, it’s best to avoid liquids and powders.

On the other hand, if you want more control over how much treatment you use, then liquid and powder are better options.

Compatibility

If you’re searching for an RV black tank treatment, you might come across treatments that aren’t suitable for your tank. Make sure to choose a treatment suitable for the type and size of your tank. 

Benefits of Using RV Black Tank Treatments

If you’ve never used an RV black tank treatment in the past, you might not realize what you’re missing. Below, we explore the obvious advantages of using this type of treatment in your RV’s black tank.

Odor Elimination

One of the worst parts about traveling in an RV is that you must transport your wastewater. When you flush your RV toilet, all your sewage stays onboard until you can empty your tank. Unfortunately, this results in foul smells entering your RV.

While these foul smells are semi-contained due to the design of many modern RVs, they still leak through.

One of the primary benefits of RV black tank treatments is that they remove these septic smells. Some treatments mask it with another scent, while others seek to neutralize the odor.

Either way, this odor elimination benefit can make your trip much more enjoyable.

Waste Breakdown

Another core benefit of using RV black tank treatments is the waste breakdown. As waste builds up in your black tank, it can solidify or create a dense sludge.

This sludge makes it much harder to clean out your tank, and it can also add to the foul odors associated with black tanks. Most black tank treatments will liquefy waste and are an excellent way to prevent unnecessary buildup.

Paper Breakdown

One of the most overlooked benefits of using a black tank treatment is the paper breakdown. If you’re using tissue paper or toilet paper in your RV, it can sometimes cause problems for your septic system.

Many RV owners have to purchase particular types of toilet paper that don’t clog up the septic system.

If you use the right type of black tank treatment, you won’t have to worry about clogs. The treatments are strong enough to break down toilet paper and can prevent septic issues from the stubborn paper in your system.

Still, while this is a definite advantage of using black tank treatments, we recommend following your RV manufacturer’s instructions. While these treatments do an excellent job of breaking down toilet paper, it’s best to be cautious unless you have no other choice.

Keep Your Black Tank Clean

While breaking down waste and eliminating odors are the primary purposes of these types of treatments, they also keep your black tank clean. Treatments keep your tank in much better condition by reducing the amount of waste buildup and solids in your tank.

It’s a good idea to find a high-performing treatment if you want to maintain your RV’s condition and its waste system.

RV Black Tank Treatment Types

As you can tell from our list of the top five products, there are multiple types of treatments currently available on the market. Let’s explore the four most common options in more detail below:

Powder Treatments

Powder treatments are the most common form of RV black water treatment. They allow the RV owner to measure out custom amounts of treatment. If you’re someone who has a huge tank, using powder treatments ensures that you’re not restricted by pre-set measurements.

Liquid Treatments

Liquid treatments are similar to powder treatments because they allow users to customize the amount of treatment in the tank. With liquid treatments, you typically pour the liquid into your RV toilet bowl, add water, and then flush it into your system. If you don’t think it’s providing enough odor relief, you can simply add more.

Pod/Capsule Treatments

In recent years, pod treatments have become increasingly popular. While they don’t provide the same measurement flexibility as liquid or powder treatments, they are much easier to use.

You won’t need to worry about spilling highly-scented liquid or powder in your RV.

Tablet Treatments

While tablet treatments aren’t as commonly available as other options on our list, they are still available from many black tank treatment producers. Unlike capsules, tablets don’t use concentrated liquids to treat your tank. Instead, they use compacted powders to fight odors and waste buildup.

The Importance of Environmentally-Friendly Products

When you use a black tank treatment, it can be easy to forget its impact on the environment. Sourcing effective products is essential, but it’s also critical to consider the environmental impact of the product.

Fortunately, there is a growing trend toward eco-friendly black tank treatments. Many of the best RV black tank treatments on our product list benefit from biodegradable features and other environmentally friendly features.

If you want to avoid harmful chemicals, it’s best to double-check that products don’t contain formaldehyde. While this chemical is extremely effective at reducing odors and breaking apart waste, it’s both dangerous for humans and harmful to the environment.

There are now plenty of cheap, natural options available on the market, so there’s no need to use toxic chemicals if you don’t have to. 

RV Black Tank Treatments: FAQs

We receive a lot of questions about RV black tank treatments. If you’re trying to find a black tank treatment for your RV, make sure to check out the questions and answers below. And feel free to contact us if your question isn’t answered.

What is the Difference Between a Black Tank and Grey Tank?

If you’re new to RVs, you might be confused about RV terms. In most RVs, there will be a “black tank” and a “grey tank,” which contain different types of wastewater. The black tank is the main sewage tank that receives the wastewater from the toilet in your RV.

On the other hand, the grey tank is a tank that receives water from your sink and other non-sewage sources. While the grey tank water is still dirty, it doesn’t require the same level of waste management as most black water tanks.

Still, some people do choose to treat their grey tank with treatments to reduce odors and prevent uncleanliness.

What Are RV Black Tank Treatments?

RV black tank treatments break down waste and reduce sewage odors often present in the black tank of an RV. Doing so creates a much more pleasant environment inside the RV.

How Do You Use RV Black Tank Treatments?

The way you use an RV black tank treatment will vary depending on which type of treatment you’re using. Most treatments require you to place the liquid, powder, or pod in your RV toilet bowl and add water.

Once there is enough water to facilitate the treatment’s benefits, you flush the toilet and let it work its magic.

Can you add bleach to your RV black water tank?

Yes. If you want to clean your RV black tank, you can mix water with bleach and use it to clean your tank. While this isn’t an excellent way to mask odors and break down waste over extended periods, it’s still a good option if you’re seeking to clean and sanitize your tank.

What’s the Best Way to Clean an RV Black Tank?

While RV black tank treatments help keep your tank clean and smelling fresh, you will still need to perform some extra cleaning when you empty your black tank. In most cases, there will be leftover residue and waste that you need to remove. Check out our simple 5 step process to clean an RV black tank!

Can You Make A Homemade RV Holding Tank Treatment?

Yes, you can make a simple and effective holding tank treatment using supplies you likely have lying around your house. Check out our guide to the best homemade RV holding tank treatments for more information.

Are There Eco-Friendly RV Black Tank Treatments?

These products help protect the environment from harsh chemicals and toxins. They also protect your family from exposure to chemicals harmful to their health. Camco TST Ultra- Concentrated Drop-Ins are a great example of an eco-friendly and biodegradable treatment!
