The Walex Porta-Pak Deodorizer is our BEST VALUE treatment simply because of ALL these features at an affordable price!

So… Are There Any Downsides to This Treatment?

Despite having the convenience of being packaged in PODS, this may be a disadvantage for others. This is because you have NO WAY of accurately measuring the solution.

Likewise, ADJUSTMENTS are all dependent per pod.

You may have to use MORE than what you may have intended or needed in the first place.

Pros

  • Convenience of individual capsule pods
  • Great odor elimination
  • Long-lasting and fast-acting treatment
  • Ample capacity for treatment

Cons

  • Immeasurable potency

Best Budget Pick: Camco TST Ultra Concentrated 41197 RV Toilet Treatment

Camco 41197 TST Ultra-Concentrate Orange Scent RV Toilet Treatment, Formaldehyde Free, Breaks Down Waste And Tissue, Septic Tank Safe, Treats up to 16-40 Gallon Holding Tanks (1 Gal)

Key Features

  • Odor Eliminator
  • Citrus Scent
  • Cost-Effective
  • Liquid Type

The TST Ultra Concentrated Treatment from Camco is an AFFORDABLE liquid concentrate treatment. This is our BEST BUDGET PICK.

The Camco TST Ultra Concentrated is no different from its capsule and pod-type counterpart because it sports the signature ORANGEY CITRUS SCENT.

This offers a REFRESHING ALTERNATIVE to the usual flower scents famous in RV black water tank treatment.

Cleaning Mechanism

This liquid concentrate may not be as convenient as its pod counterpart, but it INTEGRATES better in the water!

The TST Ultra Concentrated Treatment can DISTRIBUTE MORE EVENLY inside the RV black tank.

This makes its tank treatment AND deodorizing effect more EFFECTIVE… not to mention MORE appealing to an RV owner, too.

Usability

Liquid treatments are also often PREFERRED because YOU control how much you can use.

Just 2 OUNCES of the liquid concentrate can TREAT A 40 GALLON RV HOLDING TANK.

The deal is especially cost-effective because you do NOT need to apply A LOT to treat such a HUGE CAPACITY TANK.

To use the product, simply follow these two steps:

  • Lightly dilute 2 ounces of the product in water
  • Flush the resulting concentrate down your RV toilet bowl into the septic system

This should ALSO be strong enough to BREAK DOWN WASTE such as toilet tissue paper, so don’t worry about possible clogging!

And another great thing? You can freely adjust the AMOUNT that you put into these black tank treatments… all because it is a LIQUID TYPE.

So… Are There Any Downsides to This Treatment?

Liquid black tank treatments usually encounter STORAGE problems:

  • Space. Unlike pods in packets, these are stored in BOTTLES or GALLONS, which occupy a relatively larger space.
  • Leakage. The product may experience LEAKAGE if the bottles are NOT tightly sealed.

The Camco TST Ultra Concentrated is susceptible to these downsides, so MAKE SURE that you store it properly!

Nonetheless, the product does its job ALL at an affordable price.

Pros

  • Affordable
  • Concentrated liquid formulation for RV black tank treatments
  • Easy to control dosage
  • Fresh citrus scent

Cons

  • Storage space
  • Possible packaging leakage

Best For Beginners Pick: Walex BIO-11530 Bio Pak Waste Digester and Odor Eliminator

Key Features

  • Ten Individually-Packaged Pods Per Pack
  • Natural Enzyme Formula
  • Non-Staining and Safe for Septic Tanks
  • Can Break Down Both Waste and Paper
  • Pod Type

The Bio Pak Waste Digester and Odor Eliminator is ANOTHER product from Walex on this list.

We believe that the Bio Pak product is a GREAT ENTRY LEVEL black tank cleaner that you should consider. THIS is why it is our BEST FOR BEGINNERS PICK!

Walex has always been a pioneer of sanitation and odor-control manufacturing products. This ensures the QUALITY and SUSTAINABILITY of the Bio Pak.

That said, the product effectively targets GREASE, SLUDGE, SOLID WASTES, and SEWER SMELL in their black tank treatments.

Cleaning Mechanism

The Bio Pak Waste Digester and Odor Eliminator employs an enzyme-based formula.

This mechanism is what enables the product to do the following:

  • Eliminate tank odors
  • Replace odors with an alpine scent
  • Eliminate waste buildup and toilet tissue to unclog
  • Eliminate the risk of bacterial growth in the gray tanks AND black tanks
  • Eliminate the risk of staining your tanks

The product also does NOT contain any potentially harmful chemicals. This ensures the safety of its black tank treatments!

Of course, all thanks to the enzymatic reactions that break down the waste NATURALLY.

Usability

The packaging of the Walex Bio Pak in pods allows it to be used EASILY:

  • Ensure that your toilet or drainage has ENOUGH WATER
  • Drop in your Bio Pak pod into the toilet
  • Flush the toilet to introduce the RV holding tank treatment

As pods, this Walex product does NOT require any more measuring or scooping.

Simply introduce the formulated package to your black tanks, and you’re GOOD TO GO!

So… Are There Any Downsides to This Treatment?

Pod treatments only suffer from the disadvantage of WHOLLY USING EACH POD when making adjustments.

Since the measurements are pre-set, one RV holding tank treatment may require MORE THAN ONE Walex Bio Pak pod… of course, depending on the size of the tanks themselves.

It may also take some time to dissolve! Remember that these are PACKAGED PODS and not immediate powdered RV black tank treatments.

Nonetheless, the AFFORDABLE PRICE POINT at which Walex offers the Bio Pak Waste Digester and Odor Eliminator is GREAT NEWS for RV owners.

Pros

  • No harmful chemicals
  • Odor control
  • Convenient and intuitive usage
  • Affordable price
  • Instant results

Cons

  • Does not dissolve quickly
  • Possible multiple pods per single RV black tank treatment
  • Limited number of pods per pack

Green Gobbler Holding Tank Deodorizer and Treatment

Green Gobbler Holding Tank Deodorizer and Treatment | RV, Marine & Porta Potty Treatment | Prevents Clogs & Waste Build-Up (10 Pod Pouch)

Key Features

  • Odor Eliminator
  • Waste Breakdown and Digestion
  • Declogging Feature
  • Pod Type

The Green Gobbler Holding Tank Treatment is a GREAT odor-eliminating product.

With an odor preventing formula that helps facilitate the declogging of your RV toilet, Green Gobbler offers an effective cleaner at an AFFORDABLE price.

Cleaning Mechanism

The Green Gobbler Holding Tank Treatment uses water-soluble pods that achieve the following:

  • Dissolve waste products from the drains
  • Unclog drainage and septic tank system
  • Delivers long-lasting odor prevention for toilets

These basic features help maintain the HEALTH of your holding tanks.

Maintenance through the use of treatments regularly is ideal for keeping your tank systems CLEAN AND OPERATIONAL.

Usability

Here are TWO WAYS on how to properly use the Green Gobbler pods:

  • Flush ONE POD down the toilet, or
  • Throw ONE POD directly into the holding tank

Flushing down the pods into your RV toilet helps ELIMINATE WASTE from these drainage systems as well.

On the other hand, direct tank treatment is suggested if your drains are STILL working perfectly… of course, with the hindsight that the tank has an ACCUMULATION OF WASTE and is causing foul odors.

So… Are There Any Downsides to This Treatment?

Drop-ins are pre-measured and portion-controlled.

These are disadvantages because you do NOT have specific dosages to follow. This means that treatments are never made specific to your needs.

However, it does come at the advantage of CONVENIENCE… for which pod types are specifically made for in the first place.

Overall, the Green Gobbler Holding Tank Treatment is a great all-around alternative for your tank treatment needs!

Pros

  • Intuitive pod usage
  • Odor control
  • Effective holding tank maintenance
  • Affordable

Cons

  • No specific dosing because of portion control

TankTechsRx RV Holding Tank Treatment & Cleaner

TankTechsRx - RV Holding Tank Treatment & Cleaner - 33.8 ounce = 68 treatments - All Natural Probiotics for RV, marine, camping, portable toilets

Key Features

  • Odor Neutralizing
  • Probiotic Solution
  • No Harmful Chemicals
  • Suitable for the Treatment of Black Tanks and Gray Tanks
  • Liquid Type

The TankTechsRx RV Holding Tank Treatment & Cleaner is one of the MOST VERSATILE black tank treatments in the market right now.

It is a product perfect for you if you are SENSITIVE TO SMELLS.

This is because RV black tank treatments most of the time come in a VARIETY OF SCENTS: fresh, citrus, or floral… so while popular, you might ALSO want to consider an RV tank treatment that is simply NEUTRALIZING.

If such is the case, then the TankTechsRX tank treatment is the one for you.

Cleaning and Odor Neutralizing Mechanism

The TankTechsRx RV Holding Tank Treatment & Cleaner uses a bacterial solution for a NATURAL and ENVIRONMENTALLY FRIENDLY RV black tank cleaner.

It is a SAFE probiotic solution that you can use around your family and pets.

Moreover, these probiotic bacteria also LIQUIFY WASTE more effectively for dumping waste into your black tank.

So as a TREATMENT, it can do the following:

  • Neutralize odors. Rather than relying on SCENTS to overpower the smell of the septic system, it merely MASKS THEM to produce no odors.
  • Remove struvite crystals . These are BUILD UPS in the walls of your tank that cause slowing of drainage, failure of tank sensors, and trapping of doors.

Tank Compatibility

What’s great about the TankTechsRx Treatment is that you can use it to clean your black tank, grey tank, and galley tank!

Most tank treatments usually just offer effectiveness over ONE kind of tank… TWO if you’re lucky.

However, that is NOT the case with this product. To use it correctly, simply follow these two steps:

  • Add a small amount to your RV toilet bowl
  • Mix this with an arbitrary amount of water
  • Flush the toilet bowl

You do NOT have to worry about the amount of treatment! This is because the product is a “one size fits all” kind of treatment.

So… Are There Any Downsides to This Treatment?

You are assured great value for your purchase.

  • Effectively neutralizes odors
  • Straightforward and versatile usage

This is convenient because you have the FREEDOM to choose which type suits your needs best.

So… Are There Any Downsides to This Treatment?

The Aqua-Kem liquid formula may provide instant results upon use, but it MIGHT be less convenient than its drop-ins counterpart.

This is considering any packaging problems that may result in leakage AND user preference… and concerning this, some users report a strong hint of its chemical smell.

It is also priced higher than most holding tank treatments.

Regardless, the product is still one of the best RV black tank treatments you can get.

  • Powder Type

The Unique RV Digest-It is a great alternative to your black tank cleaner.

Cleaning and Odor Control Mechanism

The product uses a bio-enzymatic formula to BREAK DOWN AND DIGEST the solid waste inside the RV black tank AND ELIMINATE ODORS.

These bacteria use solid waste, urine, and toilet paper as their food source… this effectively produces the ENZYMES that further break down waste to PREVENT CLOGGING.

Unique RV Digest-It achieves this WITHOUT the use of outdated chemicals:

  • Without the chemical formaldehyde or bronopol, the product is deemed SAFE for septic systems AT HOME OR IN RV CAMPGROUNDS

Following these steps helps PREVENT SENSOR MALFUNCTION.

Remember: cleaning and removing solid waste BEFORE it clings onto the RV tank’s sensors prevents system misinformation. It provides accurate reading for a better travel experience!

So… Are There Any Downsides to This Treatment?

The Unique RV Digest-It Holding Tank Treatment merely MASKS THE ODOR. It eliminates unwanted smells BUT does not introduce a new scent.

Depending on your preference, this might be a downside that you should highly consider before purchase.

Pros

  • Instant results due to powder dissolution
  • Intuitive usage

Buying Guide: Here’s What to Look For When Choosing the Best RV Black Tank Treatment

There are FOUR FACTORS that we recommend you look for while choosing the RV tank cleaner for you:

  • Type of Treatment
  • Treatment Purpose
  • Septic Tank Compatibility
  • Affordability

All of course, with effectiveness as a standard.

#1 Type of Treatment

Effectiveness does NOT depend on the type of treatment. Rather, they account more for your CONVENIENCE.

Options for RV black tank treatment come in two types: tablets and liquids.

Tablet or Pod Treatments

These types are MORE CONVENIENT to use.

You simply just have to put the pods in the tank and WAIT for the results. Oftentimes these drop-ins also involve the facilitating of an RV toilet.

What’s great about this is that you do NOT have to worry about LEAKAGE or SPILLAGE.

Powder Treatments

Powder types are easier to MANAGE than pods.

This is because you can CONTROL the amount that you put in!

You may consider formulating the treatment mixture. One advantage of doing so is you save on extra expenses and resources.

Liquid Treatments

The CONVENIENCE with a liquid treatment is that you simply have to FLUSH the contents down the toilet.

The only difference is that you have to MEASURE the liquid beforehand. You should also be wary of LEAKAGE or SPILLAGE due to its packaging.

#2 Treatment Purpose

Your purpose dictates the type of chemicals you should use. Purposes could include:

  • Odor control
  • Curtail the growth of germs
  • Bacterial growth control

You should also check if the chemicals used are BIODEGRADABLE.

A biodegradable black tank treatment would usually have NO FORMALDEHYDE as an ingredient.

This is useful to know if the product will naturally disintegrate before serving your treatment purpose.

#3 Septic Tank Compatibility

You should determine the compatibility of the type of chemicals with the BASE MATERIAL OF THE SEPTIC TANK after identifying them with your PURPOSE.

The choice for your black tank treatment could CAUSE UNWANTED REACTIONS that manifest through:

  • The formation of foul odors, or
  • The degradation of the tank material

Ensuring this compatibility could help you AVOID any issues in the RV toilet system.

#4 Price

The CHEAPEST product is NOT always the best RV black tank treatment.

Here are QUESTIONS you should ask yourself when taking into account the price of the treatment:

  • How many treatment sessions does the product entail?
  • How many tablets or pods are provided in one pack?
  • How many times can you use the liquid in the bottle?
  • How much of the product is needed for one treatment session of a 40-gallon capacity holding tank?

More than being INEXPENSIVE, RV black tank treatments should be COST EFFECTIVE and VALUABLE.

FAQs

What Are the Types of RV Tanks?

There are two types of HOLDING TANKS in an RV:

  • Black Water Holding Tank. The black tank collects water from the toilet.
  • Grey Water Holding Tank. The grey tank collects water from the shower, kitchen sink, and bathroom sink.

Tank treatment is necessary regardless of type! This is to ensure the quality of your HOLDING TANK ODOR and ABILITY TO BREAK DOWN WASTE.

What Is a Dump Station?

Simply, this is where you DUMP the contents of the holding tanks.

Here’s what you should generally do at a dumping station:

  • You should ALWAYS dump the BLACK TANK FIRST
  • Ensure that you have a proper WATER HOSE to facilitate water transfer
  • Only then should you dump the contents of a GREY TANK

This order helps CLEANSE the sewer hose after the opening of the grey tank.

Why Is Black Tank Treatment Important?

Black tank treatment is important because of these primary reasons:

  • Maintains the hygiene of your RV
  • Keeps the drainage AND sewage system of your RV clog and odor-free
  • Eliminates growth and propagation of harmful bacteria
  • Dissolves solid wastes and toilet paper to prevent clogging
  • Helps keep the tank sensors to give accurate readings about the status of your tanks

Conclusion

Maintaining the healths of your RV’s black tank and grey tank are essential responsibilities as an RV owner.

Ultimately, the choice for the BEST RV black tank cleaner for you depends on these factors:

  • Type of Treatment
  • Treatment Purpose
  • Septic Tank Compatibility
  • Affordability
