    There's a very large range because each tank is a unique environment with unique requirements.

    If the primary purpose of the water change is to reduce nitrates, employ some alternative nitrate reducing measures (add a refugium, increase the sand bed depth, add more live rock, etc). A FO/FOWLR tank with nitrates consistently at 5ppm or less would logically require fewer water changes than a system with nitrates consistently at 10ppm or more.

    In a reef tank, though, water changes replenish essential elements which have been depleted or reduced, regardless of nitrate levels. I do huge water changes (50% every several weeks) on my reef tank even though nitrates are undetectable at all times.

    Depends on your set up and the effects of the 10% weekly since each set up is a unique environment. If that interval and percentage changed out works for you, stick with it. Alternatively, increase the percentage and/or interval for 3 months and see if there is any improvements occur (which may or may not be evident). Make adjustments based on the results.

    Salt water replaces salt water during water changes. I occasionally top off with salt water to replace salt removed from the system via protein skimmer skimmate (were I to continuously top off with RO/DI water, salinity would gradually take a dip).

    I always do 10% weekly water changes and top off with only fresh RO water. I haven't really had to top off with saltwater, I've never seen a drop in salinity due to skimming, but maybe that's because I do a really dry skim.

    after doing a fair bit of research last night I have decided that it would not be right to keep a yellow tang in a 85 G.Some say it would be ok but I think that 100 G is absolute minimun , 125 G is more ideal.

    don't forget that it is not only the water volume which determines which fish you can and can't keep, it is also the swimming space.

    IMO, an 85g would suffice for a yellow tang, IF you have lots of swimming space between live rock and open swimming space. Also, length of the tank also plays a significant role in determining suitable species

    I figure I still have a few more months with out Blue Hippo Tang before he will be in need of more space. Now if I can convince my wife that we shouldn't get fish that will out grow our tank I will be so happy!
