Walex Porta-Pak "Lavender Breeze" Black Water Holding Tank Toilet Treatment Deodorizer Drop Ins (2)

Works great in a travel trailer.

so far these have worked very well in ,y black tank. we use the bathroom a lot and have not had a problem yet

This is really a good product - If you are planning to keep your black tank for couple of days, you will notice the smell - Drop a Walex porta-pak and you don't smell. You do need to clean your tank once in a while in order to eliminate all of the smell

These are easy to use, they come in zip loc bags, they do the job they are designed for, they make my life easier. We are avid RV campers. We go camping 2-3 times per month. We have a bathroom in our camper that we use frequently and I dont like smells. Upon arrival to camp, once we hook up to the water supply I will drop one in and give a couple good flushes. I have yet to have a smell. I love these. Lavender is what I have been using but I am now switching to the citrus. I have no doubt I will be happy. Yes, Im a "happy camper".

I’ve been using this exclusively for 8 years - two different campers and have never had an odor problem, even in the hot weather or when camping with a large group. I’ll never use anything else.

The product is neatly packaged and works great

I've tried a few of these products. This one I like best so far. The lavender smell is pretty strong when you open the package but not noticeable in use.

I bought these in the past and loved them. But for some reason, the outer sack on these pods does not easily disintegrate without assistance and it is not pleasant to try and open them. If you changed the formula of the pouch, please go back to what you had before. Thanks.
