• Green water → complete shock treatment, step by step

• Filter pressure rising → backwash and rinse
• Pump won't prime → prime it without burning out the motor
• Dirt on the bottom → manual vacuum or robot cleaner
• Bugs in the water → identify them and keep them away
• Chlorinator not producing chlorine → check the cell and probe
