How Do You Choose the Best RV Holding Tank Treatment?

When choosing an RV Holding Tank Treatment you should consider effectiveness, price per treatment, and customer reviews.

For many RV owners, budget is a significant concern. RVing already incurs various expenses such as fuel, maintenance, campground fees, and more. Therefore, finding an affordable holding tank treatment that fits within the budget, yet still stops odors and keeps things flowing is essential.

While price matters, it's also crucial to consider the value you're getting for the price. Cheaper treatments might seem like a good deal upfront, but if they're less effective or require larger quantities per use, they may end up costing more in the long run.

The primary purpose kinda depends on who's buying it. For example, Happy Campers customers primary point of concern is controlling odors. Second to that would be breakdown of waste and then price (depending on the customer). In this post we really want to address price, because it can be a little misleading when shopping online and you see what looks to be a pretty BIG difference in prices between brands.

Any good RV holding tank treatment should break down waste, control odors, and facilitate easier dumping. Regardless of price, effectiveness should be a top priority. Some cheaper treatments might not work as effectively or may require more frequent applications.

Before making a purchase, it's wise to read reviews and seek recommendations from other RVers. They can provide insights into the effectiveness and value of various products at different price points.

What is the GEO Method for RVs and How Do You Use It?

The GEO Method for RVs, also known as the "Good Efficient Organism" method, is a popular approach to maintaining the wastewater system in recreational vehicles. It is designed to keep the RV tanks clean and free from odors, ensuring a more enjoyable experience on the road. In this article, we will delve into the details of the GEO Method and how to effectively implement it.

To start with, let's understand what items you need for the GEO Method. The basic ingredients include water softener, bleach, and a detergent that is free from fabric softeners or bleach. These items are readily available in most stores and are relatively affordable, considering the benefits they offer.

Ingredients for Mixing One Treatment Geo Method 

After emptying and thoroughly rinsing your tanks;

Step 1:

Dissolve two cups of water softener into one to two gallons of heated water for each tank.

Step 2:

Mix 1 Cup of Dawn's original blue dish-washing liquid into each treatment. 

Step 3: (Optional) Add 1-2 caps of bleach 

Note: we're not going to include bleach as a product in our calculations.

After adding these mixtures to each tank, use your tanks normally and empty them when they’re between ⅔ full to full.

Cost and Cost Per Treatment of the GEO Method

Many RVers simply assume that the GEO method is the most cost effective treatment because you're just mixing a couple common ingredients together. However, when being use to treat RV holding tanks, this is how the pricing actually breaks down;

                   I'm no Rocket Surgeon, but the price per treatment seems pretty high.

How the GEO Method works

The first step is to add a water softener to the black tank, which helps to break down solid waste and prevents it from sticking to the walls of the tank. This allows for easier and more efficient cleaning when the tank is emptied. It is important to note that the amount of water softener used should be appropriate for the tank size, as mentioned in the method's guidelines.

Once the water softener is added, the next step is to add bleach to the black tank. Bleach serves as a disinfectant, eliminating bacteria and controlling odor. Again, the amount of bleach used should be based on the tank size and the method's recommendations.

NOTE: We never recommend using bleach in RV tanks as it is very hard on some of the parts.

After adding the water softener and bleach, the final step is to add a detergent that is free from fabric softeners or bleach to the gray tank. This detergent helps in cleaning the tank and breaking down grease and grime that might accumulate over time.

Is the GEO Method Effective?

Many RV owners swear by the GEO Method and have reported positive results. By following the guidelines and regularly applying the method, they have managed to keep their tanks clean and odor-free. However, it is important to note that the effectiveness of the GEO Method may vary depending on factors such as the frequency of usage, tank size, and individual RV's wastewater system.

For those RVers who have tried home treatments such as the GEO method, but haven't really had the success they're looking for, what should you do? We'll look at RV chemical and enzyme based treatments to fight those odors and keep sensors clean.

Should You Use Chemical Holding Tank Treatments?

When it comes to managing waste in RV holding tanks, many RV owners wonder whether they should use chemical treatments at all. Many RVers are adamant about only using water in holding tanks, while many others swear by the GEO method. Holding tank chemicals and treatments, are marketed as solutions to control odors, break down waste, and maintain a clean tank.

           Ultimately, the deciding factor of whether or not one should be used usually boils down to whether or not the camper is experience odors that they simply don't want to be smelling in the cabin. 

However, there are pros and cons to consider before deciding whether to use chemical RV holding tank treatments. In this blog post, we will explore the benefits and drawbacks of these treatments, helping you make an informed decision about their use.

Understanding the Purpose of Holding Tank Treatments

Holding tank treatments are products designed to enhance the management of waste in RV holding tanks. They typically come in liquid or tablet form and contain a combination of chemicals, enzymes, and bacteria. The primary goals of these treatments are to control odors, break down waste, and maintain a clean and functional holding tank system. It is important to evaluate the effectiveness and potential drawbacks of these treatments before incorporating them into your RV waste management routine.

Benefits of Using Chemical RV Holding Tank Treatments

One of the main benefits of using chemical RV holding tank treatments is their ability to control odors. These treatments often contain deodorizing agents that help mask or neutralize unpleasant smells, making the RV experience more comfortable. 

Additionally, some chemical treatments contain enzymes and bacteria that aid in the breakdown of waste. These microorganisms can enhance the decomposition process, leading to more efficient waste breakdown and reducing the risk of clogs. 

Furthermore, chemical treatments can help maintain a clean tank by preventing the buildup of residue and mineral deposits. Regular use of these treatments can contribute to the overall cleanliness and functionality of the RV holding tank system.

Drawbacks of Using Chemical RV Holding Tank Treatments

While chemical RV holding tank treatments offer big benefits in terms of creature comforts, there are also potential drawbacks to consider. One concern is the environmental impact of these chemicals. Some treatments contain harsh chemicals that can be harmful to the environment when they are released into sewage systems or dumped at RV dump stations. 

Additionally, the use of chemical treatments may disrupt the natural microbial balance in the holding tank. These treatments can kill off beneficial bacteria that are essential for waste breakdown, potentially leading to a less efficient system over time. Moreover, some chemical treatments may leave behind residue or create a film on the tank walls, which can interfere with accurate tank level readings and require additional cleaning efforts.

Enzyme Based RV Holding Tank Treatments

Enzyme based treatments primarily use live bacteria and introduce enzymes that break down waste into the system. These treatments contain natural enzymes that help break down waste without the use of harsh chemicals. Enzyme-based treatments can be effective in controlling odors and promoting efficient waste breakdown while being more environmentally friendly. Another alternative is the use of natural additives, such as vinegar or baking soda, which can help control odors and maintain a clean tank. Additionally, proper tank maintenance practices, such as regular cleaning and emptying, can contribute to a healthy and functional RV waste management system without the need for chemical treatments.

The decision to use chemical RV holding tank treatments ultimately depends on personal preferences and priorities. While these treatments offer benefits such as odor control and waste breakdown, they also come with potential drawbacks, including environmental concerns and disruption of the natural microbial balance. 

– Ralph Wooddell, production manager and co-owner of Chempace Corp. One thing I couldn’t agree with more is a great point made by Andy J in his post on, in which he states;

            “A healthy septic system uses bacteria to digest the solids and then the ‘clear’ water is dispersed via field line or sprinklers to be absorbed by the soil. Your RV holding tanks are not a septic system. They are holding tanks — just like a chamber pot.”
