9 Best RV Black Tank Treatments Today (2019)

The bad odor from an RV toilet can easily permeate to the rest of the RV if the holding tank is not treated periodically.

Any bad smell, let alone that coming from the toilet, is sure to spoil your RV experience.

Additionally, tank treatments also help in maintaining hygiene in the RV toilet by preventing germ and bacteria accumulation.

There are two holding tanks in an RV- a black water holding tank and a grey water holding tank.

The grey water holding tank collects dirty water from the kitchen sink, bathroom sink, and the shower, while the black water holding tank is for the toilet.

Whenever you dump or empty the black holding tank, you are required to treat t with chemicals to control the bad odor and break down solids.

This is known as the black tank treatment. There are various treatments available in the market depending on your requirement.

Why is Black Tank Treatment Important?

Regular and periodic tank treatment is important to keep your sewer and septic system functional.

Black tank treatment helps in keeping the sewage system in your RV clog free and odor free.

In addition to removing the odor from the tank and preventing its infiltration in the rest of the RV, they also help in maintaining the hygiene in your RV.

They help in sanitizing the holding tank by eliminating the growth and propagation of harmful germs and bacteria.

They are also effective in digesting and dissolving waste solids as well as toilet papers to prevent any clog in the toilet.

Buying Guide for Best RV Black Tank Treatment

The key parameters for selecting the best black tank treatment include the type of treatment, treatment purpose, septic tank compatibility, type of chemical compound, affordability and cost-effectiveness, deodorization properties, and biodegradability of the substance used, along with its efficiency and effectiveness.

Treatment Purpose

There can be various reasons behind why you want to do a black tank treatment apart from the usual periodic treatment.

Depending on if you want to do it specifically for odor control or to curtail the growth and multiplication of germs, you can go for different kinds of chemical compounds that are used for treatment.

While formaldehyde based compounds, as well as enzymes, are used effectively to control bacterial growth, nitrates are often used to control bad odor.

Therefore, depending on the purpose of treatment you can use different chemicals.

Type of treatment

There are two available options for RV black tank treatment- tablets and liquids.

Tablets are a fairly easy and convenient option. All you have to do is put the tablet in the tank and wait for the results.

It also does not cause any leakage or spillage and is a non-fussy treatment.

Liquid, on the other hand, is also extremely convenient. It requires you to flush the liquid down to the tank, much like any other chemical.

The only additional task is to measure the liquid before putting it in.

Spills are a frequent occurrence with liquid. So that requires some precision and carefulness. In terms of efficacy, both the treatments are at par.

Septic tank compatibility

The chemical compound you chose for the black tank treatment, should be compatible with the base material of the septic tank.

You need to be specifically aware of all the treatment your septic tank needs.

In case of a compound that is not compatible with the base material, there might be reactions in the degree of foul smell or even degradation of the base material.

Checking the compatibility of the compound with the base material will help in ensuring that the tank treatment does not create any issues in the RV toilet system.

Chemical compound type

Chemical compounds help in breaking down the waste so that it is easy to discharge and do not leave any bad odor behind.

These compounds kill the bacterias present and also assist in inhibiting its growth.

For example, formaldehyde is one compound that was popularly used to inhibit bacterial growth in tanks.

However, because of how strong it is, it tends to kill all kinds of bacterias even once that is beneficial.

The inhibition of helpful bacteria might create further problems in your septic tank.

Nitrates on the other hand release oxygen in the septic tank allowing the helpful bacteria to process the sewage. This results in no odor from the bacterial breakdown.

Enzymes also perform a similar function by releasing oxygen into the tank.

There are many choices of compounds used for the treatment of the black tank depending upon your requirement.

It is recommended that you properly investigate your choice of the chemical compound before the treatment.

Price

Price is an important factor when buying a black tank treatment. It is not enough to go for the product that is the cheapest.

If the treatment is not effective or does not provide a quality outcome, then the inexpensiveness is also a waste of money.

Important factors to consider here are how many times you can use a certain product, how many tablets or packets of liquid are provided in one pack, or how many times you can use the liquid in the bottle.

The consideration should not just be inexpensiveness then but also cost-effectiveness.

Deodorizing power

Many treatments, while providing a nice fragrance, fail to deodorize the tank. Masking of the black tank smell with a fragrance is different from deodorizing the tank.

Deodorizing involves completely removing the bad smell of the tank, not essentially masking it.

When you are in the process of treating the black tank for bad odor, you should check of the treatment is crafted to deodorize the tank.

There are various tank treatment options available that are fragrance-free.

Biodegradability

Biodegradable or eco-friendly treatments are becoming increasingly popular these days.

While buying the black tank treatment you should check if the chemical is biodegradable. This essentially means no formaldehyde based ingredients.

You should also check if the product will naturally disintegrate, without the help of an acid or chemical.

How Do you Deodorize an RV Black Water Tank?

The process of deodorizing the tank can be completed in three steps. The first step involves clearing any clog in the tank to ensure complete draining of the tank. This is followed by scouring to rid the tank of the dry or semi-dry remains, followed by putting the treatment and rinsing the tank.

The smell from the RV black water tank does not just go away because you were careful to flush every time you used the toilet.

The smell tends to keep accumulating and invade the space of your RV. deodorizing the tank, however, is not as difficult as it may seem.

And doing this periodically will only help in maintaining the hygiene of your RV.

The first step is to clear all clogs in the RV black tank. Clogs can lead to accumulation of smell over a period of time and also disrupt the cleaning process.

It is, therefore, important that you get rid of the clog first so that the tank liquid can be easily drained.

This should be followed by scouring of the tank itself.

This is done in order to get rid of all the dry or semi-dry waste that is still hanging to the sides of the tank. After this, put the treatment of your choice and let it sit before draining it for a few minutes.

This should help in deodorizing the tank. In order to be sure of ridding the smell, you might want to clean the toilet bowl and flapper as well, ensuring that there is no clog or germs.

Here is a video guide on How to use Black Tank Treatments

Types of Holding Tank Treatments

There are essentially four types of holding tank treatment which includes chemicals or formaldehyde, enzymes, minerals and salts, and bacteria. Bacteria are extremely popular and highly recommended because it performs both the function of waste digestion and odor elimination single-handedly.

Before choosing the black water tank treatment that is most suitable for your needs, you need to know all the various types of tank treatments available.

Holding tank treatments majorly come in four variations, though there can be multiple variations under them.

These four major tank treatments include chemical or formaldehyde, enzyme, minerals, salt, bacteria. These treatments are discussed individually below in brief detail:

Chemical/formaldehyde

This was popular mostly at a time when other products were relatively few.

It covers the smell of the toilet by a stronger smell or odor, often not a good fragrance, but does nothing to breakdown the solid wastes.

It is now known to cause cancer in people and is a potentially dangerous chemical.

Enzyme

Enzymes are non-living proteins that function to break down waste. They are used to break down waste but do not help in deodorizing.

They work extremely fast and can function even in extreme temperatures. However, they might not be able to eliminate waste, but simply break them down.

Mineral/Salt

Minerals and salts are used in black tank treatment to chemically neutralize odor. However, they are not functional towards the breakdown of waste and may not be able to cure clogs.

It is important that you check the ingredients of the salt/mineral treatment to ensure safety.

Bacteria

Bacteria is a natural waste digester and odor eliminator.

They eliminate odor by replacing the anaerobic bacteria with aerobic bacteria.

This is one of the most popular and highly recommended black tank treatment as it is the only option that both digests waste and eliminates odor.
