typical water changes.....?

Yep, there dozens of methods to get it done -- they all will get you to the end result. The least I would personally recommend is once a month, but as OrionN shows -- if you're diligent once per month can work just great

...Then there's those oddballs who get by never changing water... too many variables in this hobby to attribute to one place, I guess

I change out 10% a week on my 200. The reason though is not to "remove" nutrients but to "replinish" trace elements. A good stong skimmer along with some method of PO4 reduction, or dosing with carbon and live bacteria will keep your tank clean and your corals looking happy.

Today I did a 2g water change on my BC 29g tank. Added Chemi Pure Elite and dosed Iodide for all the shrooms in the tank.

I have been having good results with 10 gallons weekly. 180 gallon display with a 56 gallon sump only half full though. So I would say 200 gallons total area but with rock and all my sand Im guessing around 160 gallons or so of actual water.

A quick growing macro will do wonders for nutrient removal but just be careful if its in your display as it can overgrow a tank fairly quick.
