I do 10% every 10-14 days thats 12.5 gallons, or when my nitrates get over 10ppm whichever comes first, usually the 13-14th day.

10 gal a week on my 90 gal, 5 gal a week on my 29 gal, and 3 gal a week on my 12 gal. So about 10% on my 90gal and 20% on my nano tanks.

I use to change 5 gals twice a week but I noticed some loss or colors in my monti’s. I do around a 7-10 gal change every week or two now.

10-15 gal a week on a 100 gal system or more depending on how the tanks coral look, IE polyp ext and color. Any trace of Algae and i do more, The glass is a good indicator if it needs cleaning more than once a week it's too much and up the W/C volume.

40g Display, 20g cryptic fuge, half full 20g sump
I fill a 5g bucket full enough to carry it from one room to the next. i'd guess 4.5-4.75g every week. My stocking is low for my total volume (5 small fish) and I dose mag and 2 part as needed
