"Water Changes" how often do we really do them?

I have a 65g and change 1g a day m-f. total of 5g a week. And every 2 weeks I do a 5g WC on the weekend to clean my substrate with a gravel vac. But I used to just do 5g a week.
 
5 gallons twice a week on my 300 gallon total volume system. no skimmer - very large fuge. once a month i do 15 gallons instead of the normal 5 gallons on one particular day to siphon both overflows and detritus out of the parts of the sump where it collects
 
1000 gallons, I change 50 gallons every 2 to 3 weeks, depending on what else I have to do on maintenance day :)
 
25 gallons whenever I want which comes out to about one water change every four months. Corals and fish are fine not much algae growth either; its from running an over sized skimmer and not over feeding. Clean up crew helps keep detritus from causing problems and good flow helps keep it from settling.

With an oversized skimmer I could see prolonging a water change. I've pushed the limit so to speak when I kind of lost interest in the tank a couple years ago. Holding back on feeding heavy and a good cleaning crew goes along way:}
 
I have 180 gallons and probably change about 25 gallons every 6 months or so. I was religious about it on my old 55 gal, but have not done much on my 180. I am not saying what I do is right, but everything has been doing very well. The params I test for are all great. I do not skim, but I do have a 55 gallon tank as a fuge and also have a DSB.
 
12 Gallon with a 2 gallon wc every 3 weeks, really started to cut back, from 2-3 gallons I did religiously every week. As I've watched my tank mature, I've really started to note the importance and benefits of stability. Filtration is simple, 2 Rear Chamber filled with Carbon, and AC70 filled with Chemi Pure Elite.

Reefkeeping/fishkeeping in general is nothing short of an intimate relationship, where both the keeper and tank grow together.

More than anything else, its about knowing your tank; test kits and guidelines can only tell you so much, but its the knowledge of your tank that serves you best.

40g w/15g sump
every 7-10 days 5g then 10g alternating. On the 10g days I pull all pumps out and give a good scrubbing, but on all water change days the top layer of my sand bed gets vacuumed too.
 
Ok, I've got a complete noob question here.

I've got a 55g and I've never changed the water out. I've got a leather coral who, despite my best efforts, has clung to life, but it's a mere shell of what it was when I bought it. I'd kind of given up on corals, but would like to put some in there, I just don't trust myself enough to keep them alive.

Will water changes help corals? Because my fish (hippo, scopus, 2 clowns, and a few others) don't seem to care one bit. My hippo tang looks great.

I toss in cubes to balance out the PH from time to time, and it seems to be working OK.

I also have one of those little ionizers in my tank, which might also be helping.

Someone educate me.
 
Wow, I thought I didn't do enough but judging from what everyone else does, I'm on the ball, lol.

I have a 150 display, 75 sump, 20 frag tank. I change 40-50 gallons every 2-3 weeks.
 
der_klug, yes some water changes would help, its good to be on some kind of routine with it. Also, your two tangs are a huge bioload on a 55g, if you get rid of one or both that will also help. Do you test for nitrates? That could be why your corals are not doing well.

Do you have any test kits and if so how old are they.
First thing I'ld suggest is test the water, then post the results so others can chime in..
Secondly start browseing here http://www.reefcentral.com/forums/forumdisplay.php?s=&forumid=104

Reef Central is the place where all your questions can and will be answered.
 
I change 40 gallons everey two weeks on a 180 display + 65 sump/fuge. I estimate around 200 gallons total taking into account rock and sand.

Do I always go through with it? I missed a change last week due to business/work, but I'm mixing the salt now for this weekend.
