Valterra Pure Power Blue RV & Marine Waste Digester 128 oz — BioBlastPlus enzymes, odour control

Valterra V23128 Pure Power Blue is a chemical-free, bacterial and enzyme-based waste digester and odor eliminator formulated to keep RV and marine holding tanks clean and smell-free.

Designed for recreational vehicles, trailers, boats and other portable septic systems, this 128-ounce bottle uses Valterra's BioBlastPlus technology to break down waste and toilet paper while controlling odors across a wide range of temperatures. The concentrated liquid is campground- and dump-station-friendly, CA-compliant, and labeled for use in both black and gray tanks. One 128-ounce bottle provides many treatments when dosed as recommended, making it a practical choice for routine maintenance between tank pump-outs.

How much product do I use per tank and how often?

Use 2 ounces of Valterra Pure Power Blue for every 40 gallons of holding tank capacity. For many RVs this works as a single dose after a full tank flush; for heavier use, add a maintenance dose each time you empty the tank.

• Standard dosage: 2 fl oz per 40 gallons
• Apply after dumping and rinsing the tank for best results
• Adjust frequency based on occupancy and waste load

Will this product work in cold weather or different climates?

Valterra’s BioBlastPlus blend is formulated to remain active across a variety of temperatures, so it continues breaking down waste in most seasonal conditions. While biological activity slows at very low temperatures, the product retains effectiveness compared with many alternatives.

• Designed for year-round RV and marine use
• Maintains bacterial/enzyme activity in typical camping temperatures
• Store the bottle in a cool, dry place to preserve potency

Is it safe for septic systems, dump stations, pets, and children?

Pure Power Blue is a chemical-free, all-natural formulation approved for emptying at campgrounds and public dump stations, and it’s labeled safe for standard septic systems. The product is intended to be non-toxic under normal use, but as with any cleaning product, keep it out of reach of children and pets and follow label directions.

• CA-compliant and accepted at RV parks and dump stations
• Safe for use in black and gray tanks and standard septic systems
• Non-chemical, biological formulation—follow storage and handling guidance

How does it control odors and handle solids like toilet paper?

The blended bacteria and enzymes target organic matter and toilet paper, liquefying solids to improve draining and reduce buildup that causes odors. Odor control comes from both waste breakdown and built-in fragrance components that leave a clean scent.

• Enzymes speed the breakdown of solids and fibers
• Bacterial cultures digest organic waste to reduce residue
• Fresh scent helps mask residual odors without harsh chemicals

Who is this for: Valterra V23128 Pure Power Blue is aimed at RV owners, boaters, and campers who want an effective, campground-friendly biological solution to maintain holding tanks between pump-outs. It’s a practical choice for frequent travelers, seasonal campers, and anyone managing gray or black water systems who prefers a non-chemical approach that’s accepted at most parks and dump stations.
