The article above provides the topic-specific context; use these checks to connect that answer to the actual fish, pond, equipment, or cultural setting in front of you.

Test the relevant water parameters and inspect flow, aeration, and filtration.
Remove excess food, debris, and runoff sources before adding a treatment.
Make one measured change, then retest and observe the fish before changing something else.

Common questions

What should I check before acting on this advice?

Does one observation prove the answer?

No. A single color, behavior, symptom, price, or pond reading can have more than one explanation. Compare it with the wider context and look for a repeated pattern before making a major change.

When should I ask for help?

Ask for help when the situation is severe, affects several fish, involves a possible toxin or injury, keeps worsening, or cannot be explained by the available observations and tests. Keep notes and product labels available.
