Each one treats up to a 40-gallon holding tank, digests waste and tissue, and controls odor for up to seven days. No formaldehyde, no measuring, no mess. Ten treatments to a bag.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eAsk any RV owner what they dread most, and the black tank is usually near the top of the list. Camco's RhinoFLEX Drop-INS take the mess and the guesswork out of it. Each single-dose pouch drops straight into the toilet, dissolves on contact with water, and goes to work breaking down waste and toilet tissue before it has a chance to turn into a problem. No measuring cups, no pouring, no splashing liquid treatment around the bathroom. You drop one in and get back to your trip.\u003c\/p\u003e\n\u003cp\u003eThe formula is enzyme-based. When the pouch hits the water in your tank, an enzyme complex activates and starts digesting waste, tissue, fats, and proteins. That's the part that actually matters day to day. Solids that break down flow out cleanly at the dump station instead of clinging to the bottom of the tank or building up around the sensors. And because the waste is being digested rather than just masked, the odor gets shut down at the source.\u003c\/p\u003e\n\u003cp\u003eOne Drop-IN treats up to a 40-gallon holding tank and controls odor for up to seven days. So for most weekend trips, a single pouch covers you start to finish. Full-timers and anyone boondocking for a stretch just add a fresh pouch after each dump. The bag holds ten treatments, which is a full season of weekend camping for a lot of folks, or a month or so of hard use.\u003c\/p\u003e\n\u003cp\u003eHere's what we like about it from a maintenance standpoint. It's completely free of formaldehyde, pesticides, and biocides. That matters because a lot of the harsh old-school treatments can damage seals over time and cause trouble at septic-based dump stations and RV parks. This one is biodegradable and septic safe, so you can dump with a clear conscience at any legal station. It also carries a built-in buffer system that stops acid formation, which is the other thing that leads to that sour, swampy tank smell.\u003c\/p\u003e\n\u003cp\u003eIf you've ever had a black tank sensor read full when the tank was nearly empty, you know how maddening that is. It's almost always gunk stuck to the sensor probes. Because RhinoFLEX Drop-INS keep waste liquefied and moving, they help keep those sensors clean and lubricated so your monitor panel tells you the truth. It won't fix a sensor that's already caked, but used regularly it keeps a clean tank clean.\u003c\/p\u003e\n\u003cp\u003eUsing it is about as simple as RV maintenance gets. After you dump and flush the black tank, close the valve, drop in one pouch, and add a few gallons of water so the treatment has something to dissolve into and circulate through. That's it. Give the enzymes water to work in and they'll do the rest between dumps. The pine scent is light and clean, not the heavy chemical perfume you get from some deodorizers.\u003c\/p\u003e\n\u003cp\u003eA quick note on where to use it. The Drop-INS are built for the black tank, and that's where they earn their keep. But you can toss one in the gray tank too if you're fighting funk from food and soap residue. Same enzymes, same job. For a tank that's been neglected, run a couple of doses back to back and let them sit a day before your next dump.\u003c\/p\u003e\n\u003cp\u003eThis is a genuinely good fit for travel trailers, fifth wheels, motorhomes, and truck campers of just about any size. First-time owner who just picked up a used trailer and wants to start the season fresh? This is the easy button. Seasoned full-timer who's tried everything? The single-dose format is hard to beat for consistency and storage. And because it's made right here in the USA by Camco, a name that's been in the RV aisle since 1966, you know it's built for the way people actually camp.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eEnzyme-based formula digests waste, tissue, fats, and proteins so solids flow out clean at the dump station\u003c\/li\u003e\n  \u003cli\u003eOne Drop-IN treats up to a 40-gallon holding tank and controls odor for up to 7 days\u003c\/li\u003e\n  \u003cli\u003eSingle-dose pouches drop straight in and dissolve in water, no measuring or pouring\u003c\/li\u003e\n  \u003cli\u003eFormaldehyde-free, pesticide-free, and biocide-free, gentle on tank seals\u003c\/li\u003e\n  \u003cli\u003eBiodegradable and septic safe for worry-free dumping at any legal station\u003c\/li\u003e\n  \u003cli\u003eBuilt-in buffer system stops acid formation that causes sour tank odor\u003c\/li\u003e\n  \u003cli\u003eHelps keep tank level sensors clean and lubricated so your monitor panel reads accurately\u003c\/li\u003e\n  \u003cli\u003eLight pine scent, not a heavy chemical perfume\u003c\/li\u003e\n  \u003cli\u003e10 treatments per bag, roughly a season of weekend camping\u003c\/li\u003e\n  \u003cli\u003eMade in the USA by Camco\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Camco reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow large a holding tank does one Drop-IN treat?\u003c\/summary\u003e\n    \u003cp\u003eEach single Drop-IN treats up to a 40-gallon holding tank.
