I would speculate that TOA is concerned with reduction of light levels
and getting the water too soft when peat is used to create
"blackwater" type conditions. I would not see peat in the substrate
doing the same things.

Well I don't know. Just making uneducated guesses here. If they told
you Duplagan was just peat water, you probably won't pay $12.98 for
500 ml, would you?
