Some people consider the drop in variants because they are convenient to use and do not require measuring before using. Portion control is what many love about this kind of holding tank treatment. These tablets are easier to use than the ultra-concentrated ones because they don’t cause spills.

There is also the liquid type of tank treatment, and some people prefer it than the drop in variants because they are ready to be flushed. It is convenient to use, but you have to do the measurement yourself. You should also be careful using it because of spill danger. But then, they are as good to use as the tablets because they’re also made of high quality and effective waste digesters, usually bacteria-enzyme formulations.

Digests even the toughest tissue brands

How We Picked

We have several options regarding holding tank treatments, so we should carefully pick one that will meet our needs. In this review, we’ve researched for and compared different holding tank treatment products, including tablets and ultra concentrated liquids.

To help you further in the comparison process, we have listed below some of the things we have considered in reviewing the top picks we’ve highlighted today.

Types

Holding tank treatments come in two types – the tablet form and the liquid form. In this review, we’ve picked products belonging to these two types. Although they have the same function, they just vary when it comes to convenience of use.

Some RV owners prefer the tablet form because they don’t have to do the measurement when deodorizing the toilet and septic. They just have to toss it in the toilet, wait for it to dissolve and then flush the bowl. The treatment will then soak into septic and start working. The enzymes are going to break down the waste materials and sludge, keeping your septic system functional and free from clogs.

The same things are what ultra-concentrated types do. They also dissolve waste solids and eliminate odor in the holding tank. Some RV owners prefer this form because they don’t need to wait for it to dissolve. They can readily flush it into the toilet bowl and then it starts working.

Biodegradability and eco-friendliness

When picking a holding tank treatment, you should look for one that does not harm the environment. Choose one that contains no formaldehyde releasing ingredients. Also, check that the product is biodegradable – that means it will naturally disintegrate or break down without chemical aids.

Effectiveness and efficiency

We reviewed the products also based on their efficiency and effectiveness. Those we have featured above are approved by the marine and RV world and the RV camping community. They can dissolve waste solids and materials in the sewer and septic as well as completely eliminate odors.

Some of these products can be used in treating up to 40 gallons of wastewater. Each drop-in or an ounce of a liquid holding tank treatment can also treat both grey and black RV water.

Affordability

The price is another thing we considered in choosing the best RV toilet treatment, but we also checked on quality because we believe the price alone should not be the basis to pick this kind of product. What comes in here is how many times you could use the product per purchase. How many tablets or packets are in one pack? How many times could you use liquid form per bottle? So the bottom-line here how cost-effective the holding tank treatment is?

Deodorizing power

We also picked based on the deodorizing ability of the holding tank treatment. In most cases, it should not only mask the bad smell with a fragrance. That said you should not base the selection only according to the scent variant of the holding tank treatment. In fact, there are holding tank treatments that are fragrance-free, while some come with a fresh and clean scent.

What they digest

Another thing we considered is its digesting ability. What kind of wastewater materials can it digest? The best of them can digest waste solids and even the toughest tissues around.

There you have some things we have considered in the review of the products we have featured above. We’re hoping you picked up valuable information when trying to compare different holding tank treatments yourself. If you would like to start with the selection process, you might also want to refer to the top picks list we have here.
