Water Changes

With such a large tank, you could easily drop down to bi-weekly water changes. I do 40G water changes bi-weekly on my heavily stocked 180g SPS tank. 40G bi-weekly, for your setup, should definitely be enough.

Agreed. You'd be better doing 40g every other week instead of 20/wk. I do 50g /biweekly and I'm satisfied with that.
BTW, you can't change too much water You can spend too much money doing it, but bigger water changes are never bad.

In my 95 gallon I do a 14 gallon water change bi-weekly with no issues with corals or livestock.
