We have had issues with our Black Tank smelling in our Season Campsite.We always used this for years. But others told us to try others from Thetford etc. Well biggest mistake ever.It took every weekend for 6 weeks to put the recommended amount in. And Yes we used a Flusher wand etc. But we would boil 2 large pots of water and dump them in with the amount of OdorLos and leave it settle for the week. And come back and the smell was finally gone. Now we fill and empty the tank like we do every weekend and always have. And now just put in the recommended amount and there you go no more odors!

We have tested out many products in the past. Odorlos seems to be the best so far. It's really too soon to be reviewing as we have only been using it for a few weeks. The test will be when it's 100 degrees outside for many days!

We've been using this for the last three years and absolutely love it. No problems with odor even if you use just one scoop.

I have been using this for 6 years now and have no complaints. It really works. Absolutely no bad odors and no issues with toilet paper becoming a problem. My level probes stay clean. The trick is to travel once in a while with half full tanks and let the road agitate the liquid. I've been RVing since 1999, and Odorloss is the best. Only complaint is the lid of the bucket. Can be a pain to pull off.

I hoped that all of the reviews about the packaging were exaggerated. I had hoped I'd be the lucky purchaser with no packing problems. Alas it was such a mess! After spending the time trying to get all the granular product back into the package it was easy to use. 2 scoops 1 gallon of water in toilet bowl. Dissolves quickly with a swirl of the toilet brush. I won't purchase again. Sticking with the liquid even though this is more cost effective.

This is my go to RV holding tank odor control product. Been using in several RVs over the last 15 years. Been very happy with it.

We are full timers with children, and we have tried MANY different brands including Happy Camper. We just always come back to this one! It gets the job done even in the hottest of temps!We prefer the granules in the bucket. We can stack a few on top of each other under the sink!We've never had a clog. If we are somewhere for a few weeks, we flush the black every Friday! On drive days we will occasionally put a little in the grey tanks to slosh around. Its amazing what it'll clean out of there!I don't think we will ever use anything else!

The product itself is great. VALTERRA as a supplier is terrible. We have ordered twice now through them and both times the product broke open and ended up undeliverable.

As a full time RV resident, I love this tank treatment. I dump once a week and have very little odor. I've used several different brands over the years and this is the best at odor control. I will never order anything else again.

Perfect for keeping boat head holding tanks from smelling. Use after every pump out. We've used nothing else!

We are full-time RVERS and we love this product. We never have problems with smells in our black tanks and it helps to break toilet paper down.
