Green pools happen fast. Heat, rain, or low chlorine and within 48 hours a clear pool turns green. The fix is well-understood: balance pH, triple-shock with calcium hypochlorite, run the filter 24/7, brush daily, clean the filter as it loads. Most Denver green pools clear in 3 to 7 days depending on severity.

Light green (bottom visible): single shock recovery, 48 to 72 hours. Cloudy green: triple shock, 3 to 5 days. Opaque green: triple shock + floc + partial drain, 5 to 7 days. Swamp green (visible debris): drain-and-clean recommended.
Chlorine is dramatically less effective at high pH. Adjust first. Then triple-shock with calcium hypochlorite after sunset for maximum effectiveness.
Filtration is what removes dead algae after chlorine kills it. Pump runs continuously through recovery. Clean or backwash the filter as pressure rises. Top off water if vacuuming to waste.
