I never asserted to “blame the right,” in my argument, just stated that even under ideal conditions algae happens. Your initial assertion was that the tidal water was to blame. I merely stated that the situation is more complex and other factors could be contributing as well.

The article you provided states that algal blooms happened prior to the switch to tidal water, which provides evidence against your initial argument, that tidal water is the cause.

The article you sited is not a scientific evaluation of the reflection pool fails to provide any data on the frequency of algal bloom events, the chemistry of the water, and the impact of the local environment (even if it comes from a reputable source). Scientists are trained in knowing the difference between opinion/hypotheticals and data driven papers.

You eluded to multiple factors in your follow up comment that I agree with, such as frequency of monitoring and overall management. These factors and other potential unknowns could be contributing to the blooms.

Many pools filled with potable (drinking) water grow algae if the chemicals are out of balance. Blaming the water source may seem like the easiest answer, but there are a lot of factors to consider. Here’s a reputable pool website discussing pools with algae problems and how to treat them.
