Cloudy pool water can be dangerous to your health as it often indicates the presence of harmful bacteria, parasites, and contaminants. Never swim in cloudy water - clear it first using proper shock treatment.
Yes, you must rinse pool filter sand both before installation to remove dust and debris, and after installation through backwashing. Proper rinsing prevents cloudy water and ensures optimal filtration performance.
Yes, pool pH can definitely be too high. When pH exceeds 7.8, it causes cloudy water, reduced chlorine effectiveness, equipment damage, and skin/eye irritation. Lower it gradually with muriatic acid or sodium bisulfate.
Sand in pool filters should be changed every 3-5 years when it becomes worn and stops filtering effectively. Signs include cloudy water, shorter backwash cycles, and decreased water flow.
Yes, you absolutely need a pool filter - it's legally required in most areas and essential for swimmer safety. Pool filters remove debris, contaminants, and particles that chemicals alone cannot eliminate, preventing cloudy water and health hazards.
Pool filter sand should be replaced every 3-5 years or when you notice decreased filtration efficiency, channeling, or cloudy water that persists despite proper chemistry. Signs include poor water clarity and reduced filter run times.
Vinyl pools do need calcium hardness, but at lower levels than plaster pools - typically 150-300 ppm compared to 250-350 for plaster. Too low causes corrosion, too high causes scaling and cloudy water.
