Whether yours turned while you were out of town or has been sitting a while, we bring it back to clear and safe, then set up a routine so it doesn’t go that way again.

$280 to $455+ across the DFW area, depending on the size of your pool.
A figure with a plus on it is a starting price. Bigger pools, and ones that have been let go a while, get quoted after we see them. Not sure which size you have?
The shade of green and the chemistry tell us whether this is a quick recovery or a multi-day job, and we tell you which up front, not halfway through.
Once the debris is out and pH is right, we shock the pool and brush every surface so the sanitizer can get at the algae.
The filter runs around the clock to clear the water, then we vacuum the dead algae off the bottom, shocking again if it needs it.
Once it’s clear, we’ll set you up on a weekly plan so the chemistry never drifts far enough for algae to come back.
True Texan Pools keeps your water swim-ready all year, across Plano and the rest of DFW. Clear pricing, a photo report after every visit, and Austin doing every job himself.
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.
Steady weekly service is the best prevention there is. Keeping sanitizer and pH where they belong, brushing regularly, and running the pump enough hours a day stops algae before it ever blooms, especially through the hot months.

Most green pool articles tell you what to add. This is the log: the number that ends each stage, how long each one honestly takes, and the checklist for when it stalls.

Three parts per million of free chlorine, and the walls still feel slick. The problem isn’t the chlorine number, it’s the number you’re reading it against.

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.
