Came off kind of preachy though

Psychographic is again right of course. But algae growth is sometimes good, it show you have an environment in which life can thrive. Just eliminate that algae. Maybe get some macro algae to take up the nutrients the micro algae is using. This way you can take advantage of the high nutrients, and still have something cool to luck at. There are literally thousands of cool macros out there. They are also inexpensive compared to coral.
