Just my thoughts.....

I would respectfully disagree.
Small water change is Less stressful then one big one even if this means cleaner water, this does not mean large change of any sort is good for you inhabitants.

You might want to try this. Reduces nitrates like a dream. However it doesn't cure the problem (if indeed you do have one). But better than a billion water changes (while good for the tank, not so good for the back)

Takes about 24 hours to reduce nitrates and phosphates. Clouds up the water for a bit (its clay-ish) but then clears. Pretty neat product

Remember some one mentioned that German tanks with creasy SPS colors had a haze to it? They use clay too, to increase skimming and No3 reduction.

Right, but you don't have to use it every day do you? I have used it in my tank and it clears completely after about 24 hours. Seems funny that they'd put it in their tank and then take the photo

I have done 50% water changes every 2 days for a week on my old 75g tank with no stress what so ever. In fact because i was fixing major water quality issues at the time, I only saw a huge improvement with every water change

All of this just proves my skimmer on the 175g sucks . I took it offline for 2 weeks and all it did was increase my fretfullness, no nitrates, no extra glass cleaning, nothing.

Here is a good article to read about water.

http://reefkeeping.com/issues/2005-10/rhf/index.php

"The normally encountered differences in calcium, magnesium, alkalinity, nitrate, phosphate, silica, pH, etc., are unlikely to unduly stress organisms during water changes up to 30-50% using natural seawater or aerated artificial seawater, in my opinion."

In this article it says up to 50%. You do need to be aware of water temp and a few other things, but I'm still not convinced that a fish/coral living in a toilet that needs flushing, is better than flushing.

I have read a few articles stating this or similar types of opinions and even one up to 80%.

I think alot depends on how bad the nitrates are.
