Reef Nano: How often water changes?

Hey guys,
I'm finally starting to get some corals into my tank. I have a 14g nano and no protein skimmer and I was wondering how often I should be doing water changes to keep up the minerals for my reef? Once a week? Once every 2 weeks? And how much? Since my tank was cycled (December, 2008 ) I've been doing 3g water changes approx. once every two weeks. Yesterday I added the duncans (which eat meat and are photosynthetic). What do you think?

Thanks, Kristyn.

p.s.- I'll be posting some picture updates of my tank soon The percs are starting to blacken and they are so cute, and the sixline has the best personality ever! I love my tank!

 

I have a 12g Nano Cube and usually do a 1 gal. change every week.

 

I'd say keep goin with what you got goin on you seem to have a rutine running for ya... And of course keep a eye out for coral changes and water chem levels to adjust your water changes acordingly..
I two have a 26gal Aqua pod.. I have a lil false perk with tons of personality..!!

 

Ok, sounds good

 

FWIW, I dont have much of a bioload at all. but on my 20 Long on either do a weekly 2 gallon change or a bi-weekly 5 gallon change, Depends on my mood and work schedule. : )

 

I think he does water changes because like many of us , its ingrained =10% weekly or 20% fortnightly = it is what we do innit

question for you Missionsix - do these comments apply to larger tanks? have I just changed 5 gallons of water depsite all my test kit readings being fine - simply because thats what I do every week?

what about minor and trace elements you cant test for ? and I was conditioned to believing you should not add anything that you are not able to test for and thus doing the water change helped to maintain those

 

Thanks for all of your help guys.
