What do San Marcos homeowners ask about green pool recovery?
How fast can you clear a green pool in San Marcos?
Most light-to-medium green San Marcos pools are swimmable in 24 to 48 hours. Severe swamps with black algae or heavy organic debris can take 3 to 5 days. The pro sizes it up before starting.
Can I just shock my green San Marcos pool myself?
You can, but it usually doesn't finish the job. Shock without consistent filtration, brushing, and follow-up chemistry reblooms within a week. The whole protocol matters, not just the chemical dump.
Do I need to drain my green pool in San Marcos?
Almost never. Even heavily green pools recover with chemical treatment and filtration. Draining is a last resort when stabilizer (CYA) is way too high or physical debris is beyond filtration.
