Definitely the best way to keep your boat pumpout in good condition. Easy to use: you just pop it in the loo after having a pump-out. Gives the loo itself a good clean, and stops the pipes clogging up which is a horrible thing to fix. Not cheap, but worth paying for. We have used for years. Recommended to us by Kris Cruisers in Datchet, who use it in all their hire boats and also stock it.

Fresh scent and completely dissolves all solids! Don’t waste your money on the cheaper orange product, it’s nauseating & does not dissolve anything.

Have used many different types and this one so far is the best. Eliminates odors from the system while in the tank and while cleaning out. Keeps your tank clean during flushing. Helped to remove years of build up in the system.

This was the first rv tank deodorizer I purchased from rv dealer. My local store did not carry this brand. I tried the brands I could purchase locally. They did not work as well as this brand. It eliminates odors better than the other brands.

Easy to use, easy to store, seems to take care of odors really well (boat doesn't smell like heavy chemicals either). Only complaint is several pouches are kind-of stuck together, and they tear easily if you try to separate them. Also, be very cautious handling around water... the wrapper dissolves almost immediately in contact with water. But, very happy with these over using bottles.
