I live and breathe water changes.

Big tanks,all five get 50-60% a week.
Betta tanks (1 gallon and up) are done once a week
Betta containers with juvies are done every other day. They're the most time consuming and the toughest of all to stay on top of but ya gotta do whatcha gotta do.

EDIT~ forgot to mention my grow outs and nurseries which are done every day. (How could I forget !?!)

Depends on the tank. Most get 50% weekly, Hatching tanks will get 50% daily for a week or so, then slowly cut back. If I'm trying to get some serious growth going on fry, I'll feed them as much as possible & do 75% weekly.

Usually 50%-60% on my 55gallon and 20-30% on my 20gallon

EDIT: Once a week

At least once a week (1/3 - 1/2). I just made water change couple days ago (1/3) and couple hours ago (1/3). But basically once a week. Somethimes I do 3/4 water changes to get rid of old water.
