unable to increase kH to increase CO2 concentration. I've never needed
to
add CO2 with a reactor before, so there must be something else I missing.

You had pearling without added CO2 and with less than 2 watts per gallon?
How is that possible?

Dunno, it was as I said before I moved.

How far away did you move? Are you in a different water supply? I bet it's
something in the new water.

Moved less than 5 miles. You're probably right about it being something
lacking in the water.
My first thought was PO4, but prior to the move I always had kH around 5 out
of the tap,
so maybe the soft water is contributing.

I'm no chemist, which is why I posted all the relevant water chemistry.
Maybe someone can explain how I can increase the kH without the pH going
through the roof and killing all the fish. I'm acceptable to all
suggestions.

Regards
Graham
