Why Is My Pool Green? A Plano Owner's Green-to-Clean Guide
A green pool in July is not a mystery, it is chemistry plus Texas heat. Here is why algae takes over so fast in DFW and the exact steps to clear it back up.
From swamp to swim-ready, then kept that way.
A green pool in the Texas heat is not a mystery, it is chemistry plus temperature, and it can happen in just a few days. Whether your pool turned over a long weekend or has been neglected for a while, we bring it back to clear and safe, then set up a routine so it does not happen again.
We read the shade of green and the chemistry to judge whether this is a quick recovery or a multi-day job, and set expectations up front.
After clearing debris and balancing pH, we shock the pool and brush every surface so the sanitizer can reach the algae.
We run the filter continuously to clear the water, then vacuum the settled dead algae out, repeating shocks if needed.
Once clear, we recommend a weekly plan so chemistry never drifts far enough for algae to return.

A lightly green pool can often clear in 24 to 48 hours. A deep green or swamp pool can take three to five days of repeated shocking, brushing, and running the filter around the clock. Severe cases sometimes need a partial drain.
Shock kills the algae but does not remove it. Clearing a green pool also requires brushing every surface, running the filter continuously, and vacuuming out the dead algae. Skipping those steps is why a pool often turns cloudy gray instead of clearing.
Consistent weekly service is the best prevention. Keeping sanitizer and pH steady, brushing regularly, and running the pump enough hours a day stops algae before it can bloom, especially through the hot months.

Chlorine, pH, alkalinity, calcium, cyanuric acid. Here is what each number should be for a North Texas pool, why our mineral-rich fill water changes the math, and how to keep it balanced.
