Post your test results for pH, ammonia, nitrites and nitrates. If you change 50% of the water when nitrates get to 40ppm then you will be at 20ppm afterwards. Get a test kit with regeants and test tubes for this if you don't already have one.

I like to change 50% of water when nitrates get to 20ppm so that the nitrates never get higher than 20ppm.

If you normally do 50% water changes I would do one right now to gradually get the nitrates lower. However gasping for air at the surface may not be related to high nitrates.

I can't read the card and your's is different than mine. What is the test item on the right? Is the nitrite test missing?

Definitely change 50% of the water, if you have been doing 50% all along. Change less if you have not been changing 50% every week for a while. Too abrupt a change, even though the water is cleaner, can kill your fish.

All the test results are important, not just nitrates. Ammonia and nitrite are also toxins...and more dangerous than nitrates. Too many toxins for all tests. Change 50% of the water as soon as possible, if your fish are used to 50% changes every week.

How did you cycle your tank?

Something has caused toxins to overwhelm the beneficial organisms. It seems you are in a mini cycle.

**All of the 50% recommendations are dependent on whether you have been doing 50% regularly in the past.

So, please post the numbers for ammonia and nitrite and nitrates after your 50% water change to see where we are.

Plan on doing 50% again tomorrow morning and probably 50% again tomorrow night.

It wasn't mentioned in your posts but are you using or do you need to use a dechlorinator for your new tap water? If so, what product are you using and how much are you adding to the tank?

Is the only thing that changed was the addition of the crushed coral? Why did you add it in the first place?

Are you adding anything else to the tank such as buffers, plant fertilizers or anything else?

Whatever is causing the problem (and we are still figuring that out together) the fish will take a couple of days or more to heal and show improvement. If your nitrates went from 80ppm (in picture) to 10ppm) in your report of test results after the water change, that drastic of a change can harm your fish.

How much did the pH change when you added the crushed coral, if any? pH is a parameter you also want to change slowly...less than 0.02 per day. A drastic change in pH can also cause fish distress, which is why it is so important to monitor.

Even if you had gill flukes or ich or another disease, first you need to remove the toxins in your water. Are you saying you put in more water? How will that help, by diluting the toxins?

You probably have no disease at all, just the poor water quality.

No I put crushed coral in to help buffer water when doing big water changes I change 50% twice a week now as my nitrates after 4 days are 40/60 ppm not water quality

Nitrates of 40ppm are marginally safe. I still think it is water quality.

Also if the nitrates were over 40ppm for any length of time, from the point when your nitrates are 20ppm or less, it will take days for your fish to recover and for symptoms to stop.
