Thetford Campa-Fresh® Free & Clear RV and Marine Holding Tank Treatment, 16-Ct Toss-Ins (96726)

love this. the smell is not overpowering very mild but there. these toss ins are fairly inexpensive. they were shipped quickly to me by Walmart. at dump time after flushing you just drop a small toss in and add some water and it keeps your tank fresh and clean. i have tried many. these are the best.

I used this often for my rv after I cleaned the black tank out and filled it with a bit of clean water. I always put it there before we go back to home so it helps break down everything in there. High recommend!

I am retired and live in a motorhome. This is the brand I use to deal with my black water tank. I love the delivery system Walmart has developed

I was looking for the best product recommended by campers and this was it. I was glad it could be found at Walmart.

These packs make RV camping very easy. They are just tossed in the toilet and done. Easy and effective.

These definitely did the job. Our camper never had an odor during our latest trip. Easy to use and does the trick... my kind of product.

Works well. Helped break stuff down

This product work well in the heat

I didn't receive the item dispite my conversation with support they assured me the driver would know not to place package in yard with 10 dogs I was told I would get a reship and pro'code for the error it to was a lie

don't buy this you will be so mad.. my black tank was 1/3 full and it was smelling so bad.. so i put another pod in and still it was wrong. (the orange ones are the best for odor. ) but to top it off i can't return this product and i don't know why.. it's been 2 weeks since i purchased them. now if there is something that can not be returned it's should be posted on the page so you know..
