I'm not sure if there is an answer to this question, but I'm hoping all you pond experts can figure this out! I have a 3 year old established pond with goldfish varieties. For the past few days, "Spot," my favorite fish, has been swimming continuously in circles. The water is still pretty cold, so all of the other fish have still been in "hibernation," except Spot. I've examined Spot, and I notice nothing wrong with her externally. I tested my pond water with a liquid test kit, and all values are perfect. It was evening when I tested it, and my pH was 8.2, BUT my pH has always been high in the pond (for the past 3 years, and that's how old Spot is). Should I be worried about Spot? Another thing I can't explain is that I set up a patio pond about 3 weeks ago. It is about 30 gallons with a few fish that are doing fine. I used media from the existing pond to cycle the new pond. What's interesting is that when I tested the water in the patio pond tonight, my pH was 7.2. I'm not sure why the huge difference between my readings.
