How often do you do water changes?

[Jaws]

I change 40G every month on a 180G tank. I try to do it every two weeks but it usually ends up being a month.

Everybody's schedule makes me feel bad about mine. I havent done a water change(just top offs) for 5 months now. But I will be doing one this week since I need the established tank water for a new nano

After reading all the posts I wish I had a nano tank. I do 55 gal water change weekly on a 300 gal tank. Is it a bad thing my kids college fund went into salt mix?

DUDE! That's a little nuts...well, for me, considering my aquarium IS 55 gallons, lol.

My parents spent my college fund on a time share.

I do a 40 gallon change once a month on 200 gallon system.

I'm about the same as Joe, 50g change once a month on my 220.

I do a 25 gallon water change every-other week on a 125 gallon system. I used to do weekly 3 gallon water changes on my 33 gallon. I miss those days. But the bigger tank is way better!
