“This item, unlike its competitors, arrives intact and fully usable. We bought our RV used and the toilet had an odor from the black water tank. One of these flushed down the toilet instantly solved the odor issue and the odor has not returned. It’s been a month and only used one so far!.”

About Citra-Pak
10 sachets per bag, 12 bags per case
Can I empty into a septic system if I use Bio-Pak?
Yes. Bio-Pak is an enzyme-based product, so it is septic safe.
Can I use Bio-Pak in my boat’s toilet?
Yes, you can use Bio-Pak in your boat’s toilet, because the formula is eco-friendly.
Is Bio-Pak scented?
Yes, Bio-Pak is currently available in two fragrances: Alpine Fresh and Tropical Breeze.
How frequently do I need to use Bio-Pak?
Drop a Bio-Pak down your toilet every time you refill your tank with water after dumping or once you start to smell odors emanating from your toilet. How often you do that depends on usage, but typically campers dump about once a week. After you dump, drop one Bio-Pak packet into five gallons of water for a 40-gallon tank. If you have a smaller tank, we recommend 1.25 gallons of water for every 10 gallons of holding tank area. Adding ample water is crucial because it allows waste and paper to fall below the waterline enabling the enzymes to work their magic.
Does Bio-Pak break down toilet paper as well as waste?
Yes! Bio-Pak’s powerful enzymes digest paper as well as waste.
Do I need to use special RV toilet paper if I use Bio-Pak?
No. No need for any particular type of RV toilet paper. Bio-Pak will break down and digest top-selling brands just as well.
Can I use this product in my grey holding tank?
No. Bio-Pak was designed explicitly for black holding tanks. For Grey water tank sanitation and odor control, we make a product called Elemonate, designed explicitly formulated to destroy grey tank build-up like organic sludge, grease, and food particles.
How long does it take for the packet to dissolve?
The packet starts dissolving immediately upon contact with water.
Can I use Bio-Pak in a septic tank?
Bio-Pak is septic safe, meaning that if you use Bio-Pak to deodorize your black holding tank, you can safely empty the tank into a septic system. For monthly septic tank treatment, we manufacture Bio-Active Septic Tank treatment, designed to keep septic systems healthy.
What makes Bio-Pak eco-friendly?
Bio-Pak is eco-friendly because it is free from formaldehyde and biocides and septic safe. It uses natural enzymes to digest bacteria, waste, and paper.
Can I use Bio-Pak in any climate?
Bio-Pak should be completely effective in all but the hottest climates. If you’re camping in conditions that exceed 90 degrees for hours at a time, we recommend switching to Porta-Pak.
