Thank you very much!!
Speaking of LifeReef Skimmers, they are very powerful/efficient. When I came home from work today I opened up a couple of fish books I have read a dozen times each, and made a decision to move more towards the Berlin System. I don't run a very sophisticated filtration system, so all that really means is I pulled the carbon sack from the back out. My tank will now rely on LR, the skimmer, and frequent water changes to maintain quality (plus Kalk via ATO). I sent out water samples to AWT.com yesterday, so I will have a full 11 parameter analysis to compare in another month to see what changes, if anything.
The idea here for me is the theory that carbon soaks up some trace elements beneficial to my SPS, and at the same time is almost unnecessary when combined with my already frequent/weekly water changes. We shall see once the tests return, and literally see if there are any noticeable changes in the tank (be it positive or negative).
