No measuring, no formaldehyde, and a light American pine scent. One pod per treatment, ten in the pack.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've spent a weekend in a camper with a full holding tank, you already know why tank treatment matters. Camco's TST PRO Drop-Ins take the guesswork and the mess out of it. Each one is a pre-measured pod, 1.58 ounces, that you drop straight into the toilet and flush down. No pouring, no measuring cup, no splashing liquid on your hands. One pod is one treatment, and this pack gives you ten of them.\u003c\/p\u003e\n\u003cp\u003eThe formula is bio-enzymatic, which is the honest way to handle a holding tank. Instead of masking the problem with heavy chemicals, live enzymes and bacteria actually break down solid waste and toilet tissue inside the tank. That does two things. It keeps the tank from turning into a clogged, packed-up mess, and it cuts odor at the source instead of covering it with perfume. When the dump valve finally opens clean and the tank sensors read right, that's the treatment doing its job.\u003c\/p\u003e\n\u003cp\u003eThere's no formaldehyde in it, and that matters more than a lot of people realize. Formaldehyde-based treatments can kill off the bacteria that campgrounds and septic systems depend on, and plenty of parks won't let you dump them anymore. TST PRO is septic-safe, so you can run it at a full-hookup site, a dump station, or a home septic system without worrying about what you're sending downstream. It works in both your black water tank and your grey water tank, so one pod format covers the whole system.\u003c\/p\u003e\n\u003cp\u003eHere's the thing about holding tank odor. Most of it comes from waste sitting and going anaerobic, which is a fancy way of saying it rots without enough oxygen and starts to stink. The enzymes and bacteria in TST PRO work on that waste before it gets to that stage, so you're not chasing the smell after the fact. That's why folks who switch to a good bio-enzymatic drop-in usually stop reaching for spray fresheners in the bathroom. Handle the tank, and the coach takes care of itself.\u003c\/p\u003e\n\u003cp\u003eCamco finishes it with a light American pine scent. It's not a heavy air-freshener smell. Just a clean, outdoorsy note that keeps the bathroom from announcing itself on a hot afternoon. And because the drop-in dissolves on its own once it hits the water, you're not fishing a wrapper back out or waiting around for it to break up.\u003c\/p\u003e\n\u003cp\u003eThese are made for RV and camper holding tanks, but the chemistry is the same in any comparable setup. If you've got a similar holding tank on a boat or a portable toilet, a drop-in works the same way. Drop it through the bowl into the tank with some water, and let it do the rest.\u003c\/p\u003e\n\u003cp\u003eUsing them couldn't be simpler. After you dump and close the valve, add a little water to the tank so the enzymes have something to live and work in, then drop in a fresh pod. That's it. Keep a strip of ten in the storage bay and you've basically got a season's worth of tank fills ready to go. Weekend campers, full-timers, and anybody tired of hauling jugs of blue liquid around will appreciate how little thought these take.\u003c\/p\u003e\n\u003cp\u003eOn value, a ten-pack like this is the easy way to buy. You're set for a long trip or most of a camping season without reordering, and there's no half-used jug of liquid sloshing around in a compartment. Each pod is sealed and dry until it hits the water, so they store well and travel well. Throw the strip in with your sewer gear and forget about it until you need one.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. Drop-ins are built for convenience and consistent dosing, so if you prefer to eyeball a heavy pour into a badly neglected tank, a concentrated liquid treatment might suit that job better. And in very hot weather, or with a tank that's been sitting a while, you may want to treat a little more often to stay ahead of odor. For normal camping though, one pod per fill keeps waste breaking down and the rig smelling right. It's simple, no-drama gear, and that's exactly why we keep it on the shelf.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eBio-enzymatic formula digests solid waste and toilet tissue inside the tank instead of masking odor\u003c\/li\u003e\n  \u003cli\u003eFormaldehyde-free and septic-safe, so it's welcome at campgrounds, dump stations, and home septic systems\u003c\/li\u003e\n  \u003cli\u003ePre-measured 1.58 oz drop-in pods, one pod per treatment, no measuring or pouring\u003c\/li\u003e\n  \u003cli\u003ePack of 10 treatments, roughly a full season of tank fills for most campers\u003c\/li\u003e\n  \u003cli\u003eWorks in both black water and grey water holding tanks\u003c\/li\u003e\n  \u003cli\u003eLight American pine scent keeps the bathroom fresh without heavy perfume\u003c\/li\u003e\n  \u003cli\u003eWater-soluble pod dissolves on its own once it hits the tank, no wrapper to remove\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 do I use TST PRO Drop-Ins?\u003c\/summary\u003e\n    \u003cp\u003eAfter you dump and close the valve, add a little water to the holding tank, then drop one pod through the toilet into the tank.
