I wrote an article several years ago on Aquarium pH. That is how I landed here as an enthusiat of reefing as hobby. That simple.
As a professional content writing blogger this is how I went about the writing project.
Step 1: research - find studies in support of a theory or practice such as those listed in your article.
Step 2: some discussion on the nature of the expected audience (in practice I use SEO information to identify large target audience say in this case 45 years and above)
Step 3: Decide on tone to present the info. 40 years and older tend to like to read informative material BUT NOT in the dull and unappreciative - DO this do that. Many prefer the real research tone - Research says you can have a fish tank circulating healthy water with 5 full turnovers a month. NOTE this is not procedural information this is informative - SO you can keep a fish with say less expense but maintain clarity of the water and enjoy photopgraphy - I can assist with an "improved" sample that would in my opinion get you excellent reading - Have you considered tools like Flesch reading guide
