What do you mean evaporating the reserve liquid? Are you referring to the water washes that were done after the second basification step? As long as you let everything settle before removing the water and performing another wash, there shouldn't be any harmalas in that liquid. If there is, it would settle to the bottom and you wouldn't need to evaporate it for collection. If you evaporated those water washes you probably have a lot of lye contamination.[/quote
Sorry maybe my wording. I meant after washing what remained in the the collected solution, as mentioned in the tek.
I am ph testing my batches, so no confusion over that.
I'm thinking perhaps I sucked up a tiny bit of plant material by accident, during the stage where it is removed?
Thanks firemetal, I'll probably keep it separate aswel.

Just good to know if it's active...
