I have a ten-gallon tank with two goldfish that I've owned for about two years now, and the tank is about five years old at this point. The tank was really dirty about a month ago and a friend cleaned it, but since yesterday, one of the goldfish has been acting really sick. It's sitting at the bottom and sort of gasping.
I tested the water and it showed really acidic pH levels, high nitrites and somewhat high ammonia levels. So I changed the filter, vacuumed the gravel, made a 50% water change, added Prime to lower the ammonia and some solution that helps cycle your tank and contains good bacteria.
I made another water change this afternoon but the levels are still really bad, especially the pH and the nitrites. Is there anything else I can do? I'm afraid my fish is going to die.

Edit: I wasn't really changing the water very often, I cleaned the tank about once a month or when it looked dirty, and when I cleaned it I took out about 70% or more of the water, vacumed the gravel, replaced the filter ect. I've been using API and Quick Dip Strips. The API strips just told me the Nitrite is down to 0 ppm and the Nitrate is at 40 ppm. The pH is between 6.0 and 6.5. The ammonia is at about 0.5 ppm. Both the goldfish are beginning to look sick now, they have no visible symptoms but they are both sitting at the bottom of the tank. I've been holding off feeding them for two days now to lower the ammonia.

What exactly are your numbers for ammonia, nitrite, nitrate & ph? What are you using to test your water? What has been your water change schedule (%/#wk) prior to this happening? Some more info will help us to help you better!

Unfortunately, a 10g is too small for one goldfish, let alone two. With this many fish in too small of tank, you should be doing water changes atleast every other day until you can home them properly. The lack of healthy water & insufficent water changes has resulted in the issues you are encountering. I would start doing water changes of atleast 40% until you can bring your ammonia under .25ppm & nitrates under 10ppm. Hopefully, they will be able to recover with lots of healthy water.

Thanks,
I've been doing that and testing the water with two different kinds of test strips, Quickdip and the other one I mentioned above, and the other one says that the nitrate is back to safe levels while the quickdip one says its sky high. So I'm not sure...I do know that the pH is still very acidic and my fish isn't getting any better. Is it possible that it has swim bladder disease?

What do you feed them? I would suggest getting a liquid test kit for ammonia, nitrite, nitrate & ph such as API fw master test kit. Strips are unreliable & inaccurate at best. Please read the link below for info on how to care for your goldfish.
