CamcoRhinoFLEX Premium Enzyme RV Holding Tank Treatment Drop-INs | Features a Biodegradable Septic Safe Formula, a Pine Scent, and is Ideal for RVing, Boating, and More | 10 Count (41519)

I use this in our camper black water holding tank. It breaks waste down quickly and makes it easy to dump with no real clogs and no sewer stink. I woul definitely buy them again.

This product smells great and does work as advertised. The reason I gave it an average rating is because I am using it in a porta potty and there were no directions in how to use it that way. So I'm left to guess. I think I'm using too little because I'm having a little smell. However it is doing a great job with taking care of the paper and disintegrating the poo. It has been very easy to keep my unit clean and tidy. I've never left it for a full seven days though, because quite honestly I'm older and don't want to be lifting anything heavy. It would be nice if they included some instructions on the bottle for porta potty users.

I have a holding tank on my camper. Have been camping all my life. Have used many products, as I am always willing to try. Rhino DID NOT eliminate the smell at all. Even putting in brand new, there was no smell. I will not be buying these again.

The formula seems to work well, and doesn't have any strong odors when using it.Downside is that the large size jug includes nothing to help you pour cleanly or accurately. It's just a welded-on foil seal that must be cut, a child-proof screw top, and a half-hearted ounce gauge printed on the back label. For the price, I'd expect a better gauge or dosing cup and a seal doesn't require sharp objects and drip/leak every time it's used.

We are full-time RVers and these packets work. I used two a week in our holding tank, Sundays and Wednesday or Thursday and I am quite satisfied with the odor control.

Great product works great and has a nice smell. This is the second product i have use to help control odor in RV. It works MUCH better than the other one I tried. And you use less of it.

Doing its job so far. I live in the RV with my two sons, so it holds well as far as odor but it’s doesn’t break down as well as it says, but the tank fills pretty fast too, so to be fair it works decently.

Followed the directions and it works. Had a very bad smell in my camper and now it’s all peachy

Not sure what is going on with this toilet chemical, it seems to have bits of black flakes in it. Not sure if we got a bad bottle or what but it's kinda gross. Doesn't seem to keep the smell down like other brands we have used. Glad I only bought a small bottle to try out. Will be switching back to the old brand we used when this one is done.

When you drop big fat deuces in your holding tank and let them sit to mellow and ferment these little orange bags are a must.

Arrived extremely quickly and immediately went to work doing exactly what it claims to do. I got the pine scent as we live in the woods and I didn't want anything taking away from nature. It's perfect! Will buy again for sure!

Great price, cheaper than in the stores!
