It breaks down waste and tissue without formaldehyde, controls odor for up to 7 days, and runs a clean lavender scent. Eight single 4 oz bottles, each treats a tank up to 40 gallons.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eEvery boat and RV with a head has the same problem waiting in the holding tank. Waste and paper build up, the smell creeps up through the deck, and the level sensors start lying to you. The Camco TST Lavender holding tank treatment is the drop-in dose that keeps all of that under control. It's a formaldehyde-free formula that breaks down waste and tissue in the tank so it empties clean and stays fresh between dumps.\u003c\/p\u003e\n\u003cp\u003eHere's how it works in practice. Each package gives you eight single-dose bottles, 4 ounces apiece. After you empty and rinse the tank, you pour one bottle in, add some water down the toilet, and you're set. One bottle handles a tank up to 40 gallons, which covers the vast majority of boat and RV black tanks. There's no scoop to measure, no powder to clump, and nothing to spill on your hands. Just tip it in and go.\u003c\/p\u003e\n\u003cp\u003eWhat makes this one worth keeping aboard is what's not in it. No formaldehyde. No pesticides or biocides. That matters for two reasons. First, formaldehyde-based treatments can stall the bacteria at a pump-out station or a septic system, and a lot of marinas and campgrounds won't take formaldehyde waste anymore. This treatment is safe for all septic tanks and completely biodegradable, so you can dump it anywhere that's legal to dump. Second, the older formaldehyde chemicals had that sharp hospital smell that everyone recognizes. This one runs a clean lavender scent instead, and it actually covers odor for up to 7 days between dumps.\u003c\/p\u003e\n\u003cp\u003eThe waste breakdown does double duty. As the formula digests solids and paper, it also helps keep your tank's level sensors clean. If you've ever had a monitor panel that reads two-thirds full on an empty tank, you know that's almost always crud stuck to the sensor probes. Keeping the tank treated and the waste liquefied goes a long way toward getting honest readings off that panel.\u003c\/p\u003e\n\u003cp\u003eThis is genuinely dual-purpose gear. It's RV and marine approved, so it works the same in a boat head, an RV black tank, or a fixed cabin toilet. It's even fine for a portable camping toilet, which is handy if you run a small skiff or a tender with a portable toilet aboard. One case of eight covers most of a season for a weekend boater, or a long stretch of trips for a cruiser who's careful about pump-outs.\u003c\/p\u003e\n\u003cp\u003eThe single-dose bottle format is the part that gets overlooked. On a boat, where locker space is always tight and nobody wants an open jug of tank chemical sliding around in a seaway, a sealed 4 ounce bottle is easy to stow and impossible to over-pour. You grab one, empty it, toss the bottle, and you're done. No sticky cap, no guessing at a fill line on a big container, no measuring cup that has to live next to the head. For anyone who's cleaned up a spilled jug of tank treatment in a cabinet, that alone is worth the switch.\u003c\/p\u003e\n\u003cp\u003eA few honest notes. This is a waste-tank treatment, not a tank cleaner. It keeps a tank that's already in decent shape fresh and flowing. It won't dissolve a solid clog that's already formed, so if your tank is badly neglected you'll want to deal with that first. And it's built for black tanks, though plenty of folks run it in a gray tank that's picked up a funk too. Dose it after every dump, keep a little water in the tank, and it does its job quietly.\u003c\/p\u003e\n\u003cp\u003eIf you want the marina-guy version: this is the treatment we reach for because it's simple, it doesn't stink up the boat, and it won't get you turned away at a pump-out. Eight doses per box, one box lasts most boaters a good while, and there's nothing to think about beyond dropping one in after each dump. Made in the USA by Camco, a name that's been building RV and marine gear since 1966.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFormaldehyde-free formula breaks down solid waste and toilet tissue so your tank empties clean\u003c\/li\u003e\n  \u003cli\u003eOne 4 oz bottle treats a holding tank up to 40 gallons, no measuring and no mess\u003c\/li\u003e\n  \u003cli\u003eEight single-dose bottles per package, one drop-in dose per tank fill\u003c\/li\u003e\n  \u003cli\u003eControls holding-tank odor for up to 7 days between dumps\u003c\/li\u003e\n  \u003cli\u003eFresh lavender scent instead of the usual sharp chemical smell\u003c\/li\u003e\n  \u003cli\u003eCompletely biodegradable with no pesticides or biocides, safe for all septic tanks\u003c\/li\u003e\n  \u003cli\u003eRV and marine approved, works in boat heads, RV black tanks, and portable camping toilets\u003c\/li\u003e\n  \u003cli\u003eHelps keep tank level sensors clean so your monitor panel reads true\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\u003eWhat does the Camco TST 41551 treatment actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt's a holding tank treatment that breaks down solid waste and toilet tissue inside the tank while controlling odor.
