A lot of people recommend 10% every week or so.
I usually do about 10 gallons every couple weeks in my 75 and so far that seems to be working well, however my bio-load is fairly light (only a yellow tang and 2 damsels) and I don't have any corals, yet. I may have to increase my water changes as my reef progresses.

Sorry Im very bad at math but how much is 10% in gallons for a 40 gallon?

 

[ohioreef]

10% would be 4 gallons.....
