It seems to me that you don't have an aquarium, the aquarium has you!
Do you ever go on vacation? if that's so, who does your weekly water
changes?
As far as I know, your weekly water changes replace all the filters in your
tank, might as well get rid of those because they are doing nothing to your
water.
And you only have a 55?
I have a friend that spent $3k on hardware and does water changes every 4
days, yes, almost twice a week.
I have to brag about it now, I have a 65gal with a minitank in series of 20
gal, total of 85gals on my system and haven't done a water change in a year
yet with 30 inches of livestock that is the envy of my neighbors because of
how good it looks in my favorite place.
Soon I'll be posting pictures here but until I can manage to build a better
illumination system, I have to wait!

Most people do a 15% water change once a month. I like doing a 50% water
change about once every 3 to 6 months.

I do 6 gallons change in my 55 gallon tank weekly. Because of all the
rocks and corals, it's probably more than 15%. The RO/DI has to be run
weekly anyhow, and some green algae has to be removed that often and the
additives are used weekly + the coral feeding and the anemone's weekly
shrimp diet, so it just seems convenient. Also, 6 gallons is how much fits
in the pail, so I don't have to measure the level in the tank. It just
seems all around simpler to do all the weekly stuff at once.
