Septic Tank Treatment & Holding Tank Deodorizer Tablets, 1 year supply, Bio clean Packs for RV, Marine Portable Toilets, toilet cleaning chemicals, All Natural. Must have RV accessories

Easy to use, no issues at all. I just drop it in during the first use of the cassette toilet and give a good spray out at the end of that trip. No smell the next camping trip

Easy to use and odor free. Keeps your RV black tank running smooth

really has taken the smell down, thank you

Doesn't work

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.

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.

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
