Mike,thanks,must be around 10 years now that i am in the reefkeeping hobby.
Husbandry of the system in a shortcut.
every week water change of 180 liters,so in one month around 8% of the total volume,i try to do two times in a year a bigger change,around 1000 liters in 1 change.
Trace elements for the last year is dosing strontium(home made)and from KZ kaliumjodidfluor,coralvitalizer.
Now and then i put some zeozym into the tank from KZ because it clears the water.
Every 3 weeks 1 liter carbon and around 50 mg of ozon,i put a lot off light onto the tank and that cost a lot off money on power so my intention always is too keep my water as clear *** possible too get the maximum of this light for my corals,if the water is only a little yellow you lose a lot of light and offcourse your money
I believe furthermore too give a lot of food for the fish(i must because off the angelfish)so you get on a natural way a lot off trace elements into your system.
