i guess i should of asked this before i did it ,but i just did a 50 gallon water change,.... my water perimiters where fine my nitraits where at 5.but my water seemed to have a yellow tint to it when i looked threw the side of the tank?????so i went and got a bucked of salt and did a 50 gallon water change....know im just wondering if maybe that was to much
i have a 180 gallon tank and 400 pro clear filter that holds something like 48 gallons ...
i did this sunday evening,and yesterday my corals looked kinda flumpy not opened nearly as big as they usually are and its not all of my corals manaly my leathers and mushrooms my montipora star polyps are fine .plus i did some rearanging yesterday...maybe it will pop back today hear are some pictures from this morning....



my niger he always trys to get into the pictures he is such a ham....

Corals can always be a bit upset after water changes and take a day to come back out. I think changing a third of the tank's water is fine - even half of it in an emergency - but make sure parameters like the salinity, tempereature, and pH are the same as what's in your tank.

Yellow water is usually due to lack of water changes, dysfunctional protein skimmer or full skimmer cup, and/or lack carbon or exhausted carbon that needs replaced. It can also be from caulerpa macroalgae sexual reproduction.
You can change 99% of the water at a time with no ill effects, however, the more you change at a single time the more closely the temperature, salinity, and pH should match.

Doing large water changes runs the risk of shocking and damaging your inverts.
In addition to Temp, pH and salinity; you also need to remember corals are sensitive to calcium, alk, magnesium and a host of other trace elements.
Smaller, more frequent changes are better. Just rmember, everything in this hobby that is successful is done slowly...

For yellow water I would just actively run some fresh carbon, but I've changed out all the water before during moves without matching crap but salinity and never had a problem, corals will be stressed for a day or so but they also got banged and moved about. However since you haven't done a change lately it would be a larger stressor, my tanks always get good sized changes weekly and are used to it.

I did a 60 gal water change in my 150 to get my trates down about a yr ago with no ill effects. I did make sure the water was exactly the same PH, salinity and temp first though.

I regularly do 50% waterchanges on my nano tanks (10g and 12g) with no ill effects. I only match up the temperature and slainity and get the PH as close as possible to reduce stress on inverts/fish. the corals dont care. you notice the acclimation tecnique most commonly used on corals is "temp only" shifts in parameters dont bother most corals as long as the shift stays within the corals tolerances. you can go instantly from a SG of 1.027 to 1.024 with no detrimantal effects (for corals). this happens often when I trade stuff in at my local petstore he runs his tanks at 1.024 I run mine at 1.027 no acclimation they open within minutes. (he doesnt even temp acclimate) though we do run the same tank temperature there must be some temperature drop in transport.
