by: Kpyto - For almost a year I did no water changes... just added water to top off the tank.
There is a LFS here that's been in business for 25 years and he has a tank that hasn't had a water change in 5 years.
It's full of life and looks beautiful. He tested the water right in front of my to show me all levels were zero. I was stunned. It goes to show you this hobby does not have set rules. It's trial and error and opinion. Something that works for someone may not work for someone else. Just look at all the debate over lighting. Some have great SPS success w/ T5's other swear it can't happen.
Personally, I do a 20% weekly change. I tried 2 gals daily for a while but I found that it didn't make a difference.
