Interesting thread advocating for us to clean our sand
Years ago a wise reef keeper told me to do multiple smaller changes each week. I adhered to that principle and never had issues. I then got lazy and brave with all the new "it" products. I slacked on maintenance thinking my hard earned money spent in products would carry me through. Nope.
I still believe the best method is removal via water change. Adding bacteria and other items after establishing the tank does not alleviate the situation and only masks it. <my opinion and my opinion only.
