Water Changes
I've been reading that small daily water changes are better than weekly or bi-weekly changes, but I was wondering if that was also true in a FOWLR tank. I just bought the Autoaqua AWC and I can set it to do daily changes if I need to, but I'm not sure if that advice applies in a FOWLR. I would guess that the daily changes is beneficial to corals since it is replenishing the necessary trace elements in the water on a consistent basis, but I don't see a need to do that if I don't have corals. If I do a daily water change then I am still pumping out a small amount of fairly new water every day. I am thinking that a weekly water change would still be best in my situation because I would actually be pumping out dirtier water. I know that the daily water changes minimizes the change in water chemistry, but a 10 gallon change every week in a 200+ gallon system shouldn't be that drastic anyway. Am I way off track here?

I think you are right on track.
In a fowler, I would do big water changes every couple/few weeks. You get more bang for your buck as far as diluting the waste.

My tank is 220g FOWLR, I didn't do a daily water change or weekly or monthly. I replace the filter socks every 2 day and change GFO/ Carbon every month. I do a little wet skim-mate replace them with RODI water by ATO, I add a few gallons fresh saltwater at the weekend to increase the gravity again.
I only check the gravity once a week to be sure it close to 1.026 +/- .001 (No need exactly with fish only). I feed them once a day and vacuum the sand one for every 2 week but reuse the water by put the other end of tube in the filter sock. I may do 20 gallons water changes every 6 month by skimming wet.

For the 350 FOWLR, I plan to use the strategy of 30 gallons every month and only add top-off in 5 gallon chunks as needed. The fish will not care as much as the coral in a reef would.

I replace 150-200g every 3-4 months.
