Do you pay someone to test the pool

I test it myself every few days and once a month I bring a sample to
the pool store for detailed analysis. The phosphates are a tad high
but the chlorine is dead on correct (at 4ppm).

Algae love phosphates.

That's probably what I need to test. Does it apply to black algae too?
