10% weekly is what I try to do, 20% Bi-weekly if I am busy or 30% plus a month if I am a total bum.

 

[Scuba Steve]

5 gallons a week on 100gal w/30gal sump.
5 gallons a week on 35gal hex w/20gal sump.

 

[plyle02]

5 gallons on a 70 gallon tank with 10 more gallons in the sump here...
about 7%

 

[thebanker]

<5 gallons / month that is a result of cleaning out my canister and media reactor, not an intentional water change.

I'm in Sanababit's club. haha

20% bi weekly for a 220 gallon SPS
