Yes, was planning to up pH but I stopped as goo formed.

The concentration was very high indeed. I choose about 15 to 20 mg/ml just too see if a pH depression occurs when the cloudynes sets in, simulating the situation where pH depressions occur with harmalas. No pH depression of any kind noticed with deems. A slight plateau was all, like a pH buffering effect, but no pH rollback at all.

Very likely since carbonates also gave me goo when crashing out harmalas with sodcarb (in those concentrations mentioned). Therefore (and other reasons) I preferred ammonia to avoid harmala goo.

Nevertheless I was surprised to see deems goo in the watery phase happening. This exaggerated situation learns something though, that there are potential goo mechanics in the watery base phase. Diluting might be a key here as you say, to be continued...
