Toilet question: chemical to use

[Craig V]

I found the recirculating toilet post but have a newbie question.

We bought a used TM and it came with a 32 oz bottle of "TST" RV toilet treatment by Camco.
It's directions say for recirculating toilet, use 2oz and follow toilet manufacturer's directions.

So I gather this equivalent to 8oz stuff that's noted in the manual 1 bottle of Thetford Aqua-Kem, and on the in the TM thread that mentioned CampaKem and OdorLos.

So assuming TST is the same type of stuff, should I use only 2 oz, or 8 oz when charging?

The 8oz bottles of AquaKem are pretty thick/concentrated. Can’t imagine only 2oz working to well unless it’s sludge...

I'd say it's pretty liquidy (not thick or viscous). But it also say "ultra concentrated".
See attached photos.

Personally, I wouldn't use it at all. I like the AquaKem, and as it warns, you can't mix the two.

That being said, I think you will need 8 oz to do the trick.

We like the thetford original 8oz bottles.

I still use the Thetford Aqua-Kem in my SeaLand toilet. Also, I found it interesting that the 8oz bottles are the cheapest option per oz at Wal-Mart. You’re not paying for convenience vs the big bottles.
