Again, my question is why not do a water change?

Fair enough but you can dose them. People dose Calcium right? Almost everybody with SPS...
I didn't do water changes just to see what would happen to my parameters. Just like I used a crappy Chinese LED unit to see if I could grow SPS. To see for myself.
My hypothesis being, that the
stringent water change practices people promote are circumstatial and hearsay. I do agree that water changes do have merrit and in most cases required at least once and a while.
You call me lazy, but stocking a system that can't support itself would be considered what?
