I am using the probiotic salt right now, not sure where it says and also a friend confirmed that if using probiotic you should be doing smaller waterchanges like 10%. Anyhow I still have lots of IO so for bigger WC I use that. 
The difference I've heard with the probiotic compared to the reef is that it is abit cloudy when mixing but goes away generally after a couple hrs. 
I have only done 5% wc every 3 days to remove detritous with the probiotic salt. 
Once I am done I am switching to the reef salt because I don't really notice any difference with PB vs IO.
