Buying Guide
Choosing the right black water tank treatment can feel overwhelming, but here’s what to consider:
- Odor Control: This is the most obvious factor. Look for treatments that specifically state they control odors. Read reviews to see what other RVers say about the effectiveness of different products.
- Waste Breakdown: Treatments that help break down waste prevent clogs and make emptying your tank easier. Enzymatic or bacterial treatments are generally best for this.
- Ease of Use: Do you prefer the convenience of drop-ins, or are you okay with measuring and pouring a liquid? Consider your personal preference and how much effort you want to put into each treatment.
- Environmental Impact: If you’re environmentally conscious, look for biodegradable and formaldehyde-free options. Happy Campers and Unique RV Digest-It are good choices here.
- Tank Sensor Cleaning: Clogged sensors are a common problem. Some treatments, like Happy Campers, are specifically designed to help keep your sensors clean and accurate.
- Climate: Consider the climate where you’ll be RVing. Some treatments are more effective in hot weather than others. Read reviews from people who RV in similar climates.
- Price: Black water tank treatments vary in price. Consider the cost per treatment, not just the upfront cost of the product. Sometimes, a more expensive product is actually cheaper in the long run because it’s more concentrated.
