CYA in a Bromine Pool

[waterbear]

I have been running 3 ppm FC with 80 ppm CYA but I do maintain 50 ppm borates so that might account for it.

Yup, the borates definitely take the edge off of algae growth as I've noticed in my own pool. This is consistent with the data in the text and in Table 18 in this link where 50 ppm seems to give a 50-70% inhibition in the rate of algae growth.

Funny how we seem to read the same papers.
