Ph Shock

Read this before posting!!
Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.
1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.
2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.
3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)
4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.
5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.
We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.
While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.
Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Re: Ph Shock
I don't know if it can be cured, because it tends to kill fish quite quickly. The fish is unable to adjust the water on the inside of it's body to the water outside of it - causing problems. The term pH shock is kind of generic for osmoregulation; I think it's described here as simply as I could ever describe it.

I think it's a simple case of "an ounce of prevention is worth a pound of cure."
Proper acclimation can prevent this =)

Re: Ph Shock
There is no such thing as "pH shock". It is osmotic shock. Fish do not read external pH and can tolerate quite a range of pH. Osmotic shock is quite a different matter. The sensitivity to such abuse varies with the species and the age of the fish. But it is easily avoided. Never change the fish suddenly from from one type of water to another - make such changes slowly to allow the fish to adapt so long as both conditions are within the fish's safe range. Also never dissolve material directly into tank water housing fishes - pre-dissolve the material and add that solution slowly, watching the fish for any signs of distress.
