Here is what I add to my 180G SPS tank.
Weekly 10% water changes.
Calcium Reactor 24/7
Nilsen Reactor 24/7 all top off water goes through it.
Salifert Coralline amino acids 40ml once a week.
Strontium 1 tsp daily
Carbon, 16 tablespoons once a week for 48 hours, I do this three days before my water change.
Ozone 40mg/hr for 2 hrs a day.
Clean my skimmer cup once a week and wipe out the riser tube.
Feed Live Rotifers to the tank every night 1/2 after lights out. 2 gallons run through a plankton collector then dumped in the tank(rotifers not the waters).
When I remember, I feed algae disks to the sand bed. I drop 2-3 in the tank at night. They sink to the bottom of the tank to be consumed.
I think that's it
