I'm sorry I thought I had answered. Ammonia levels were low but o tested today and it was really high. I've kept doing water changes every day but 20-30%.
I just did a 40% or so. One panda died. Ammonia must be the reason. The 2nd panda is already slow and dying. I don't have another tank sadly.
The pictures above certainly look like the tank is cycling again.
Have you got a test kit to test for ammonia, nitrites or nitrates? I think I have asked a couple of times already.
We don't know if your shrimp are now dying because of residual side effects from the disease, OR ammonia poisoning.
At this stage, I'm more inclined to assume the former (ammonia poisoning) with the lack of more information.
Have you got another tank apart from this one pictured above?
