For the last twenty + years and up to this day the majority of the hobby equates accessibility/hands in with instability.
This has resulted in lost tanks to the tune of millions of animals and dollars/rampant invasions, thousands of tanks in full invasion status needing help, to this day. What the sages should be teaching is how access causes stability, and they should be teaching accurate science behind surface area control so that people don’t feel direct access for cleaning, target kill, is some sort of luck lottery. We can access our reefs using certain steps reliably, daily, and the skill is the first notion a new reef keeper should be taught.
They should be taught the polar opposite of what they’re currently being taught about reef access...knowing when and how to place hands all the way in, to the bottom if required, creating accessibility and using that character to prevent any organism from ever taking over the investment. Today’s reefing is about us taking preps to not lose or waste any animals. in finding ways to design aquariums differently than prior decades, so we can lose and waste less, changing up access approach is first on the list
