Simple definition: Turbidity is how cloudy or murky pond water is, caused by suspended particles like algae, silt, or waste.
Detailed Explanation
Turbidity can come from a new algae bloom, disturbed substrate, or an undersized filter struggling to keep up with the bioload. It’s a visible symptom, not a single cause, so fixing it means figuring out what’s actually suspended in the water.
Why It Matters
Persistent cloudy water often signals an underlying filtration or overstocking problem, even when ammonia and pH test normal.
Practical Example
Green cloudy water usually means an algae bloom, while brown cloudy water usually means disturbed sediment or a mechanical filtration issue.
