what do you put down the loo! Forums

We notice from time to time that our loo smell. We are using aqua blue kem. What are you using? Any tips!

Hi Gem

Top tip, use nothing !

Chemicals shouldn't be used or needed in RV black tanks, they are designed to work with bacteria that chemicals will kill.. the same principle is used in a Sog toilet albeit in a smaller scale..

Hi Gem,

Looking through my Itasca manual it says use odor control. When I looked through the cupboards in toilet area I found two satchets of Thetford 'Campa.Chem, Concentrated Pre-measured Dry Holding Tank Deodorant'. I imagine it is available in the UK and someone on this site will confirm.

For sure there was a horrible smell and I have just spent the last few hours emptying, filling, taking for a drive, emptying, filling and emptying again. Just put the Campa.Chem in and about a gallon of water. I am reasonably certain that what was in there was a couple of months old! Hence the nasty wiff!

Away next weekend so between now and then I will get some idea of how good it is.

I use the crystals we buy from ABP. Nice & easy, not too expensive, and don't leave a blue stain if you spill! Like the idea of nothing at all, good price/performance ratio, but have never tried this. Des

Hi Des

We have never used any chemicals in the black tank and 'hand on heart' it's never been pongy .. if there was even the slightest unsavoury niff Jan would be up in arms Laughing

Hi All

On the first charge of the black tank after flushing the better half puts a table spoon of bio live yogurt mixed with warm water down the vacuum bog, this enhances the breakdown and we never have any back smells now not even when emptying, doesn't look good though

You could always use some biomagic. I have found it to be very good at stopping smells and because its not chemical based, its good for the environment. MHF'ers get a discount.

Hi Shane & Sally

Agreed the Bio magic is good, but not as cheap as a live culture yogurt. A small tub costs 30p ish and will be 3 doses a week. Personally we found it more efficient.

With kind regards

Your right, it is cheaper, biomagic is roughly 30p per 50ml (50ml lasts 3 days) but will it have the same gas supression effect as biomagic. The guy at the Peterboro' show biomagic stall was telling me all about the way it works to turn one gas into another, thus stopping the smells...? I really should of paid more attention, but I was sold on the fact it was a greener alternative to the blue chemicals, so the chemistry lesson was wasted on me!
