POND WATER HELP
Clear water. Stable parameters. Healthier fish.
This site focuses on pond water quality—what to test, what the numbers mean, and what to do next. If your fish are already showing strong symptoms (flashing, ulcers, gasping), use a symptom-first triage tool on SickKoi.com.

Step-by-step checklists for testing and stabilizing KH/pH, plus common mistakes to avoid.
Fast checklist (2 minutes)
- Test: ammonia, nitrite, pH, KH/alkalinity, temperature.
- If ammonia or nitrite is not zero: prioritize aeration + water change + detox/binding.
- If fish are flashing or irritated: check pH swing (night vs morning) and KH.
