I think the first time I posted a picture of my tank on this forum I was ridiculed. I'm not sure if it was the bits of hair algae, the spreading mushrooms or the less than perfect photography skills.Again I think this has to do with goal. Not everyone is worried about how effective a living room centerpiece their tank is and are more interested in the health of its inhabitants. Neither option is wrong or even hard to understand. Also sometimes people just get busy, and scraping away coralline is often far down the list as it's typically strictly a vanity venture.
I should have set up my tank to the gatekeepers goals of easy maintenance, wide and shallow, don't glue rocks for easy removal, don't build it in a wall for challenging access, don't put corals too close to the glass to ease coralline eradication.
I also let some of my lawn grow tall as well, it's to benefit riparian wildlife.
