I spent several hundred bucks on a Hach kit. On one of the tests, it said to read it when the water turned pink. How pink is pink? OK, I tried swimming pool strips. Then I sent a sample to TAMU and the pool test strips weren't far off. Your mileage may vary.
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
