thanks guys, im basically just tinkering, my gut feeling tells me corals need nutrient rich systems but obviously not ammonia and high nitrates. The ats does this.
Second i like the minimal scapes but am now convinced that you do need a good biological filtration and the cermedia biofilter is said to have the most surface area of anything out there. Before i would use bigger skimmer with little biological filtration.
Next i see little water changes as a helpful way of keeping your parameters stable, but then you have to test and dose your alk, cal, and mag.
Food wise im also tinkering with amino acids and reef chili for the corals.
Im not sure yet if this is the best way to go, but this is what has made sense to me after everything ive done and researched the last like 4 years.
