I gave up high tech some time ago, but in most of mine, the front and side glass stayed cleaner on average than my low tech tanks. Unless I keep fish that will eat them, I throw a "handful" of pond, trumpet snails, and Neo shrimp to every tank I set up though the same could be said for my LT tanks. If it's early on into bright lights and CO2, things will need to settle out. I never sought to go beyond 30 PPM CO2 though FWIW.
Nothing good happens fast in an ecosystem.
