Find Your Pool Problem
Choose what you see, then work through the likely causes in a safe, sensible order. These field-tested guides help you avoid wasted chemicals and random equipment changes.
What are you seeing?
Start with the closest match. Test the water and confirm circulation before making multiple changes at once.
Water clarity
Cloudy Water
Find out whether chemistry, filtration, fine debris, or poor flow is keeping the water dull.
Troubleshoot cloudy water →Circulation
Low Flow
Check baskets, water level, valves, filter pressure, air leaks, and the pump in the right order.
Check pumps and filters →Pool surface
Pool Stains
Identify organic, metal, or scale staining before applying a cleaner or draining the pool.
Learn the safe first checks →Surface foam
Foam & Bubbles
Rule out air leaks, product residue, low calcium, and organic buildup.
Review water-care basics →Growth
Algae
Recognize green, yellow, or black algae and understand why it keeps coming back.
Start the recovery guide →Safety first: Never mix pool chemicals, never add water to concentrated chemicals, and always follow the product label. Keep the pump running only when the system has adequate water flow.
A dependable diagnostic order
Most pool problems become easier when you resist the urge to treat everything at once.
Observe and document
Note the water color, clarity, surface condition, unusual noise, filter pressure, and any recent weather or heavy swimming.
Test the water
Use a reliable test kit. Start with free chlorine and pH, then check alkalinity, stabilizer, calcium, and salt when relevant.
Confirm circulation
Verify water level, clean the baskets, inspect the pump lid, confirm valve positions, and compare filter pressure with your clean baseline.
Make one change at a time
Follow the label, allow the system time to respond, and retest before adding another product.
