I hardly ever do water changes on my personal tanks. In most of my personal tanks I have very few fish, maybe 2 or three that I really really enjoy. For example - In my tanks I have:
1. RO Unit Auto top off
2. Refugiums with chaeto and deep sandbeds
3. Large protein skimmers that are working properly.
4. Regular monitoring of calcium and alkalinity.
I do admit that I occasionally do a 1 to 5 gallon water change every now and then - depending on what my salinity levels are, I occasionally top off with saltwater.
Then again, most people without deep sandbeds, fuges, good working protein skimmers etc. should do more frequent water changes to control waste problems.
Besides, it is good to do water changes because it replenishes trace elements and balances calcium and alkalinity levels.
Large skimmer, Alot of coral, and Few water changes is a bad idea IMO.
