Proper maintenance for me means the following.
-Mag float the glass
-Top off with RO
-20% water change
-Change filter sock
-Clean Skimmer cup
-Change Carbon/Phosban if needed
-Clean Powerheads if they need it
-Clean Skimmer pump if it needs it
-Clean Return pump if it needs it
Every 9-12 months:
-Replace my T5HO bulbs
-Replace my filters in my RO
-Scrub down and clean all my mixing equipment
That about covers my routine.
