That thread is not intended to say that forced cleaning is best. It's simply a demo of how repeatably we can rip tanks apart to the base + reassemble with skip cycle reassembly, should someone want that.
There will always be a non rinsing, hands off faction in reefing seeking true mineralization where dredge samples show neutral impacts down low, not just isolation away from water measures. Technically we need dredge samples from high/low (strata) in the bed to find the conversion point
I predict it's fertilizer but will accept correction if not. Larger tanks compound slower, the bed may measure just fine if it's new. Someone dredge for us a fifteen year hands off bed pls, I'd PayPal for such posted info
Anyone here got an old nano reef w sandbed all color infused with coralline and algae and age indicating textures? Post a dredge reading of that setup ideally
