Hello Jack. Sorry to hear your fish isn't quiet up to par.
I'm glad you have your temperature issues under control now.
I see that you've mentioned a "lowering agent" to reduce your pH levels. This is not necessary and can do more harm than good. Most fish will adapt to the pH levels that we have to offer from the tap. pH adjusters can be very unstable and even cause your pH to crash or drop drastically and result in fish loss. Here is a link on how to maintain your pH levels naturally:
Properly Maintaining the pH in a Freshwater Aquarium - Rate My Fish Tank
Since you are showing traces of ammonia in your tank, I suggest a 50%
water change and add your Prime (I see listed in your aquarium info) to detox the ammonia for 24 hours until it's time for another water change. Do the changes daily until you reach the readings that Lucy gave you, 0 ammonia, 0 nitrites and under 20 nitrates. Then your tank is cycled.
I'm not familiar with the
test kit you have mentioned. I assume it's a test "strip" kit? If so, what is most highly recommended is the
API (liquid) Master Test Kit. It will test for ammonia,
nitrite and
nitrate, pH levels. If you don't have the means to buy the entire kit at one time you can also purchase each test separately. I suggest starting with the ammonia liquid test should this be the case.
As for you fish ailments/fungus (if indeed it is a fungus)...look into a product called Melafix. Make sure you read the label and see if it's what you think might help your fish. If your fish has ICH it would look like it has been sprinkled with salt and would require different treatment. I agree with you and it doesn't sound like ICH.
Keeping your fish healthy at this point is more crucial than getting your tank cycled. However, you'll have to keep up with daily water changes. Once your fish are well then concentrate on the cycling issues. I suggest not adding Tetra Safe Start (TSS) to your tank until your fish are healthy or you could be wasting your money in the long run. Depending on if you have to medicate or not. (If anyone disagrees with this paragraph by all means speak up. Discussion is what this board is for
Best of luck and I hope your fish are going to be alright.
