Welcome to R2R. You have some good answers aboveHow old is your system?
Good morning...the tank's several years old. Got away from vacuuming sand bed...added some lost sand and have started better husbandry. Added 3 2100gph wave pumps on the loop system. Had Hydor Koralias but weren't synched. I'm hoping more flow will help with detritus.

I just run the media in my filter tray and change 10% every 2 months.
