Drop one pre-measured pouch in the toilet, flush, and the concentrated formula breaks down waste and tissue, controls odor, and keeps your tank sensors clean. Formaldehyde-free and septic-safe, each pouch treats up to a 40-gallon RV or marine holding tank. One bucket holds 30 treatments.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eBlack tank maintenance is one of those chores nobody looks forward to, and a good holding tank treatment is what makes it bearable. Camco's TST Drop-INs handle the job about as simply as it gets. You drop one pre-measured pouch into the toilet, add a little water, flush, and let the concentrated formula go to work. It breaks down waste and tissue while it keeps odor out of the coach. No measuring liquid out of a jug, no chemical on your hands, no cap to leak in a storage bay. One bucket holds 30 treatments.\u003c\/p\u003e\n\u003cp\u003eEach Drop-IN treats up to a 40-gallon holding tank and gives you around seven days of odor control per dose. The formula does three jobs at once. First, it digests solid waste and toilet tissue so the tank empties cleanly instead of leaving a mess behind. Second, it deodorizes with an original scent that covers the tank without smelling like a chemical plant. And third, it lubricates the tank's level sensors. That last one is the part most people overlook. Gunked-up sensors are the number one reason a black tank reads full when it's really half empty, and keeping them clean is what keeps your monitor panel honest.\u003c\/p\u003e\n\u003cp\u003eWhat we like about the TST line is that it's formaldehyde-free. Older tank chemicals leaned hard on formaldehyde to knock down odor, and that stuff is hard on the environment and a real problem at any dump tied to a septic system. These Drop-INs are safe for septic tanks and break down cleanly, so you can empty at a campground or a home septic hookup without killing off the bacteria that system needs to work. The formula is ultra-concentrated, and it's made in the USA.\u003c\/p\u003e\n\u003cp\u003eThis works in an RV black tank or a marine holding tank, so it's a solid answer whether you're weekending in a travel trailer, living out of a fifth wheel, or running a boat with a fixed head and a pump-out tank. The pre-dosed pouch is what makes it travel so well. There's no bottle of liquid to tip over and no measuring cup to rinse. Toss a handful of pouches in the bathroom drawer and you're set for the season.\u003c\/p\u003e\n\u003cp\u003eOne more thing worth mentioning is the format itself. Liquid treatments work fine, but they're heavy, they glug when you pour, and a loose cap in a bumpy storage bay can ruin your day. Powder scoops blow around and clump if they get damp. The Drop-IN pouch sidesteps all of that. Each dose is sealed and pre-measured, so you get the same treatment every single time without guessing. They store easily in a small bucket, they don't freeze or separate in a cold rig over winter, and they're light enough that stocking a full season's worth barely takes up any room.\u003c\/p\u003e\n\u003cp\u003eUsing them is straightforward. Start with a clean, empty tank, then add a couple gallons of water along with one Drop-IN. Don't skip the water. It gives the chemistry something to work in and helps everything break down the way it should. After that, just use the head normally. When the tank's full, dump it, rinse it if you have the setup for it, and drop in a fresh pouch to start the next cycle. That's one pouch per tank fill, up to 40 gallons. Got a bigger tank or a full crew aboard? You can step up to a second pouch without any harm.\u003c\/p\u003e\n\u003cp\u003eFor most RVers and boaters, this is a set-and-forget answer to tank maintenance. It's simple, it's septic-safe, and a bucket of 30 lasts a long time on a weekend rig. If you've been fighting tank odor or a sensor that won't read right, these Drop-INs are a cheap, easy first thing to try before you go tearing anything apart.\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, safe for septic systems and cleaner at the dump station\u003c\/li\u003e\n  \u003cli\u003eTreats up to a 40-gallon holding tank with a single pre-measured Drop-IN pouch\u003c\/li\u003e\n  \u003cli\u003eBreaks down solid waste and toilet tissue for a cleaner, easier tank dump\u003c\/li\u003e\n  \u003cli\u003eLubricates tank level sensors so your monitor panel keeps reading accurately\u003c\/li\u003e\n  \u003cli\u003eOriginal scent deodorizer controls odor for up to seven days per dose\u003c\/li\u003e\n  \u003cli\u003eBucket of 30 individual-dose pouches, nothing to measure and nothing to spill\u003c\/li\u003e\n  \u003cli\u003eWorks in both RV black tanks and marine holding tanks\u003c\/li\u003e\n  \u003cli\u003eUltra-concentrated formula, made in the USA\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 many treatments come in the bucket?\u003c\/summary\u003e\n    \u003cp\u003eThirty individual Drop-IN pouches.
