I know there has been many posts about what to use in a porta potty and I think we are going to go with the homebrand nappy san.
But is anyone able to tell us the ratios of water to nappy san? We bought our porta potty over 12 months ago but have never used it and can't find the instructions!!
The bottom tank is 20 litres, not sure about the top.
If someone is able to shed some light on how much water and nappy san in the top and bottom that would be great!!

Hi Brent & Lib
I use the same amount as i add to a large bucket to soak clothes at home; just tip a bit - probably a well heaped tablespoon, dissolved in a litre or two of water to start with. If need be, it is simple and cheap to add a bit more after a couple of days. I use plain water in top tank the same as i do at home - no additives necessary. Ours is a built in Thetford in the caravan.

What MH said, but in the top tank we put in a squirt of dish detergent just to keep things squeaky clean.......no nasty scale or stains.
No real formula....get the homebrand stuff.

Some caravanners put a bit of the same sodium percarbonate product in the top tank and i would prefer this to adding detergent.

Nothing in the top.
One teaspoon per crap in the bottom.

Does it really chew up deposits ..?
On the rare occasions we use a Porta Potty.. (and that is rare), we use Hayman Reece chemical.. and that takes up to 3 days..
No smell but ...

Bucky, Woolies Homebrand equivalent of Napisan is excellent.
Without getting tooooo descriptive, all the solids are broken down and empty out completely. We used to use Thetford brand and the solids "caked" onto the mechanism inside the cassette. Real yucky job cleaning that off.
About $7 for 3 kg. Suits me fine.

I have posted a bit more further down this thread. I would never and have never used 'chemicals' (of the formaldehyde type) in our cassette, although the previous owners had. Note if you have, you will have to thoroughly cleanse the tank (top tank too if anything else has been added) before changing to a bio type substance. Rinse very thoroughly and soak in a strong solution of the new stuff for 24 hours.

As I said it's rear that we use the Porta Potty,... (formaldehyde ? Mmmm !)
Just the shovel and roll of dunny paper, and a shrub,... natural fertilizer...
If decorum is needed then we dig a hole, use the pup up shelter...Jimmy's Thunderbox, with of course a sprinkle of lime on the deposit, to help with the smell...
Simply bloody beautiful

Thanks everyone, so do I just fill the top tank with water until it's almost full? Or I suppose it wouldn't really matter because you could just keep adding to it.
Sorry I have no idea, I have never used one before!
Bucky, yes it's supposed to be very good from what I have googled and read on here, no personal experience though.

Everytime you empty the bottom tank top up the top tank.
We try to empty ours after 3 days whether it needs it or not.
This process works fine for us without smaells and without the cost of branded chemicals.
Napisan is completely safe for septic tanks etc.

The two products most widely available that contain principally sodium percarbonate are Woolworths Homebrand Nappy Treatment Plus and Coles $martbuy Napicare Plus. Most other brands contain other ingredients and less sodium percarbonate.
We were using Bio Magic ($48 a bottle) and often only used the toilet once before emptying as we only use it spasmodically when necessary. I tried the sodium percarbonate products and was even happier with the results. There was a musty odour with Bio Magic which we don't get now.
It is considered septic and long drop safe, and when burying in the ground, the slurry disappears quickly and leaves no harmful chemical such as the old formaldehyde 'preservative' type toilet chemicals do. We have a large bottle of this from the previous owners of our van which we have never used and need to safely dispose of.
I like Peter's simple formula.
By the way Brent and Lib, your instructions probably told you not to use anything else but the brand specific chemicals distributed by the manufacturers - a bit like Toyota recommend using Toyota genuine parts not Ford.
