Happy Campers RV Toilet Treatment 18 - Extra Strength Odor Eliminator for Black and Gray Holding Tanks

This is good stuff, help to eliminate the smells, works great. Easy to use and one will last the summer season. Clear color and would recommend you to give it a try.

Whoever says this stuff doesn’t work, is crazy! Usually when I flush I get an odor (Only on the hottest days). But I did a Happy Camper treatment and immediately I didn’t smell anything, even within the bowl! Awesome stuff, easy to use! I did have to dig a little for the scoop but it says that it might be at the bottom on the package.

This product is amazing, no smell even in high heat, we use regular TP., no more expensive RV TP.

Easy to use (only one small scoop needed) and works great with absolutely no smell in our RV.

Initially i bought happy campers treatment to be used for my thetford porta potti 365. i only use the porta potti for no. 1 and only needed to be emptied around once a week.previously i use walex porta pak so i tried switching to happy campers treatment because everybody was singing praises about this product but unfortunately for me, happy campers treatment is unable to cover the odor because i could always smell urine whenever i use the porta potti and by the end of the week where i empty the waste tank, it reeks horribly :(i am not sure if my dosage is not enough or is it because the previous usage of walex porta pak has some residues remain that lower the effectiveness of happy campers but the waste tank smell horrible at the end of the week when i empty it. i tried cleaning the tank and give another shot but the smell is still bad and emptying it at the end of the week is horrible. after reading that happy campers treatment requires oxygen and does not do well in airtight environment like a porta potti, i guess i will stick back to walex porta pak for my waste tank.so i started using happy campers treatment for my grey tank instead and to my surprise, it works amazingly well! usually my grey tank will smell bad at the end of the week but ever since using happy campers treatment, the grey tank has no smell at all. it's a miracle and emptying my grey tank is a breeze now.

Easy to use.

Works wonderful

Excellent product
