Default Water changes

I just read Randy's article in Reefkeeping about water change frequency. http://reefkeeping.com/issues/2005-10/rhf/index.php

I'm sure this has been debated but I didn't find much on the search. So please humor me. What are you water change schedules? Just how much are you changing per change?
For any of you who do constant/daily water changes, what equipment are you using?

I try to do weekly 20ish gallon WCs sometimes it stretches to 10 days or 2 weeks but try to get at least 15gallons a week changed

I think it's helped me

1) not have to dose anything
2) stability
3) save money on gfo (only have to change it monthly to keep low levels
4) water and corals look super clean


I think a lot of people over look the simplicity of doing water changes and try to over think and dose and add and wonder why or what they can do to make there tank better but if you just increased your WCs I thjnk most tanks wouldn't object

For over 10yrs with my old reeftank I did once monthly 25% changes.
Now with my new reef it's 25% twice monthly.
The difference in coloration and coral growth over 8 months is definitely better as I'm sure the fish are healthier and happier too, though they haven't mentioned anything

Default Water changes

In the beginning it was 10%/week of 550g and now it's it's about 6% of 700g every two weeks or 20 days.

A 1% difference in the amount of changed water has a large impact on my total running and upkeep costs. I'm hoping to eventually arrive to a 5% monthly change by the end of this year.

I have a 90 gallon reef with a 50 gallon sump, 90 has approx.70 gallons of actual water along with approx. 22gallons in the sump, been doing a 25% WC twice a month. Seems to be working ok.
