I do 5 gallons once every..well, whenever. Why 14G? Thats about 20 percent. If its working for ya, great, but usually folks stick to 10 percent/week/month (7.5G out of a 75G tank), what ever. Is there a reason for doing so much? Algea issue, Cyano, just that bored?..
I'm am a HUGE advocate of 20-25% bi-monthly water changes on reefs. I've found everything looks better, water quality is better, corals grow faster, and the water stays noticeably clearer allowing for better light penetration. IMO, anything less than atleast 15% just won't cut. Adacaro I think 14 gals. is perfect.
I shut down everything...Tank drains back into the sump then I suck the water out of the sump. When I do large water changes I take water out of the tank as well.
