Ok nobody laugh, here's all I'm doing and none of it is etched in stone.
As far as dosing the big 3, I use the Seachem powders.
The reef builder for alkalinity and keep it between 7 and 9.
The reef advantage for calcium and keep it above 400.
The reef advantage for magnesium and keep it above 1400.
As far as replacing trace elements I use Kent marine essential elements and coral vite, I add around 40ml of each once a week sometimes 50ml of each.
I also add Red Sea reef energy A and B once a week using 40ml of each.
That's all I've been dosing for the 2+ years the tanks been setup but since I stopped doing water changes I settled on the amounts above.
For nutrient control in my sump I have a Vertex 130 skimmer, a bag of Kent marine carbon and a bag of Seachem phosgaurd, I also dose 20ml of Red Sea no3 po4 every few days or so.
I have a ton of live rock so I'm sure that helps things out overall.
Also I have a uv sterilizer.
I have a lot of fish which I honestly enjoy more than the corals so I figure if the corals are growing and colored up especially the Acros then the water is in good shape for the fish.
I have 15 fish, some would say too many and my tank is overstocked, but they are all healthy and get along great. In my mind I'm maxed out on fish and haven't added one in about 8 months.
