Features to Consider When Purchasing an RV Holding Tank Treatment

1. Types 


This type can kill bacteria effectively and prevent the development of bacteria as well. However, it cannot break down waste. Besides, it is also known as a danger to the environment. If you are sensitive to chemicals, you should not use this type as it may cause some irritation.


The enzyme is an excellent solution for breaking down waste rapidly. Specifically, it will take vast chunks such as toilet paper to break them down into small particles. The significant advantage of the enzyme is its quick operation. 

In terms of drawbacks, it cannot eliminate waste. Additionally, it is not able to get rid of odors. But if you choose a product that is full of fragrances, it probably can mask the odor. It also can cause allergies to some sensitive people. 


The nitrate serves as nutrients for bacteria when you use it for your tank. It needs a lot of oxygen to work as oxygen is necessary for breaking down the organic waste of the bacteria. If not, bacteria will take the oxygen from the sulfates in waste.

From this, the production of hydrogen sulfide is likely to happen, and this is a foul-smelling gas. This is how the nitrate treatment works. Besides, it is friendly and safe for the environment. If it works in RVs having less ventilation, it will boost the waste-breaking process and lessen the odor. 


The bioactive is environmentally friendly and helpful in sewage breakdown. An outstanding benefit of this treatment is that it can be multiple. It means that although you complete the treatment, it still can work continuously. 

But you have to ensure that the holding tank ventilates well and has no residual. This treatment seems to be slightly expensive, but it is genuinely useful. 


Salt and mineral will be used to neutralize odors chemically in this case. The advantage of this choice is that it can mask unwanted smells. But it cannot break the waste down, leading to tank clogs and backups. Besides, several substances in its ingredients car harm the environment.

2. The Overall Composition 

The composition of your options plays an important role when you select the RV holding tank treatment. You should choose a treatment whose composition does not contain harmful chemicals. 

For instance, if you want to protect the environment, you should not choose the one with formaldehyde. It is not only harmful to the environment, but it also irritates chemically sensitive people.

3. Convenience

It is advisable to search for a convenient holding tank treatment. You should avoid those treatments which easily spill when you are measuring. Besides, you also should check the holding tank treatment’s capability. 

You have to make sure that it can break down paper and waste and eliminate odor as well. So, just choose an easy-to-use product and stay away from the messy one.

4. Biodegradability

Biodegradability is a signal telling you that the product can harm the environment or not. This seems to be an essential component in all tank treatments. 

If a product is biodegradable, it can break down naturally. It surely does not use harmful chemicals. Moreover, you also take notice of the formaldehyde-releasing ingredients. This ingredient can pose a massive threat to the environment.

5. Effectiveness

As these products address disgusting toilet-related problems, you should find the one that works efficiently and quickly. 

The optimal way to decide the effectiveness of the tank treatment is to read customer reviews. The experience from other customers is beneficial as it may help you decide whether to buy that product or not.

Using the holding tank treatment for RV is relatively simple. First, you pour or drop it in a bowl. This depends on the treatment type you use. Then, you flush or soak it. 

2. How Can I Clean the RV Holding Tank?

When the tank is emptied, you can start cleaning it—first, you fill up the tank with bleach and freshwater. Then, you close the toilet lid immediately to avoid inhaling the toxic fumes. 

After 10 minutes, you drain out the tank before re-filling the freshwater. You should repeat the draining process until the water coming out is spotlessly clean.

3. How Can I Keep the Holding Tank from Smelling?

Nitrate-based products will solve this problem well. And it is the best choice as well. However, almost all the waste treatments give off an aromatic scent during the waste breakdown.

4. How Often Should I Dump My Black Water Tank?

It depends on the number of people traveling with you. Usually, you should empty it every few days. For instance, if there are two people, you empty the tank for around a week. But if there is a group, it is better to dump it every two days.
