Water quality you can measure this week (without a lab)

Temperature, dissolved oxygen basics, and clarity — simple signals that tell you when to act.

You do not need perfection on day one — you need repeatable checks. Start with what tilapia feels first: temperature swings, early-morning stress, and sudden smell changes.

Morning checks matter

Low dissolved oxygen often shows up before you see fish at the surface. Note the time of day when behavior changes.

Clarity is a teacher

Secchi-style clarity — how deep you can see a dark object — tracks plankton dynamics and helps you interpret fertilization choices.

Turn readings into actions

One measurement without context is noise. Log date, time, weather, and feeding so your next decision is informed.
