I've spoken to Dometic directly who were unable to give me a clear answer either way, however you can check out the Thetford Pink Aqua Rinse which is definately confirmed septic safe, and compatible for use with any kind of portable toilet.

Compatibility 1 answer
Is this compatible with the dometic green care waste tank tablets, and is it compatible with the thetford green waste tank tablets?

I've just double checked the instructions and there is nothing indicating that they're incompatible. So we can't see a problem with using the green waste tank tablets in the bottom tank and the Extra Care Rinse Water Additive in the flush tank.

The mixing ratio for the Dometic Extra Care Flush Water Additive is 1:100. This means 100ml of Additive for every 10L of cistern water.
