Im just currious to know how often and how much of a water change do you do? (normaly, this is excludeing if something bad happens in the tank)
I do a little smaller than a 25% water change, (more like a 23% because I dont have a 7.5gall bucket LOL) once a week

what about everyone else? :)

*edit* I meant to add once a month as well but I forgot :roll: *
 
I do PWC in my pico and nano every two weeks. In my 95 reef I do a PWC every 3-4 weeks depending on time.
 
On our 2 tanks we do 10% weekly . However our 10 in the BR is battleing algea so I have increased them to 25% weekly , since our phosphates were a bit on the high side , they are now nearing 0 phosphats

I do 50%+ every week.
I assume that's your planted tank :D

20% once a month now. Check parameters weekly and it's very stable. First year I did 20% weekly which kept everything in check.
 
20% every two weeks for me. I've tried to go longer, but my numbers start to skew (especially Calcium as I have lots of Corals). Even doing PWC's every two weeks, I still have to dose Calcium every other week.
 
10% weekly for me, twice a week occasionally if I feel really motivated :lol:
FWIW twice I decided to see what, if any, differences doing no PWC's or less frequent PWC's made(I have to dose Ca/Alk/Mag regardless b/c of coral consumption). I went about two months w/ no PWC's the first time, and just less frequent PWC's the second (but still only 10-15% for convenience sake). Both times I saw a difference for the better w/ at least 10% weekly PWC's, so that's what I do. Just my experience
