Holding Tank & Septic Tank Deodorizer and Toilet Treatment Tablets.Easy Use Packs for RV, Marine Portable Toilets, Industrial Super Strength, All Natural.

I use this periodically in a cassette toilet to freshen the tank and control odours if the tank cannot be emptied as often as would be advised.Although perhaps not the exact purpose of the product, it seems to work for my needs.

Product is described as 'tablets'; actually they are small clear bags of white powder.....I never found out if they work or not because there was no way I could carry them through airport security to get them to my boat. 🤣 Possibly they are really good but I'll probably never know.

The product was absolutely a waste of money, did nothing as described.It might as well have been belong powder.Extremely dis-satisfied !

living on a narrowboat with a waste holding tank we have used many products over the past 15 years and this one has been the only one that really works

No deodorization whatsoever, used in our RV and urine fumes throughout the van.Placed the full satchel in the loo, but sorry useless. to be dumped.

Did not remove smells as said on advert.Very expensive for not doing the job.

Very useful our motorhome. Does not take up too much space and is light and handy in the side locker.

We use these for the boat, absolutely brilliant.
