What a green to clean includes
- A full water test before anything goes in the pool
- Debris netted out, skimmer and pump baskets cleared
- Every surface brushed to break the algae layer open
- Filter run continuously and cleaned as it loads up
- pH dropped first, then shock dosed after sunset
- Chlorine held above 5 ppm until the bloom is dead
- Algaecide added after the shock, not alongside it
- Dead algae vacuumed to waste, not through your filter
- Clarifier and a full rebalance once the water clears
- A written handoff so it does not come straight back
Recovery or drain
Do you need a drain, or just a recovery?
| Chemical recoveryWater stays in the pool | Drain and cleanLast resort in North Texas | |
|---|---|---|
| Best for | Green for less than 4 to 6 weeks, equipment working | Unused for months, black algae, heavy staining |
| Timeline | 3 to 5 days | 1 to 3 days, plus refill |
| Cyanuric acid | ✓Under 100 ppm | !Over 100 ppm, chlorine cannot win at any dose |
| Dissolved solids | ✓Normal range | !Over 3,000 ppm |
| Visibility | You can see some depth into the water | Opaque, main drain invisible, black or brown |
| Surface condition | Stained but sound | Algae embedded in plaster pores, heavy scale |
| Risk | ✓None, the water never leaves | ✕Shell can float in wet clay soil, and acid washing shortens plaster life |
| Cost | Lower | Significantly higher, plus around $250 to refill |
Why it turned green in the first place
Algae blooms when chlorine falls behind, and in North Texas that usually traces to one of five things: a week away in July while chlorine burned off and nothing got brushed, cyanuric acid so high that your chlorine tests fine and does nothing, a pump or filter problem that stopped moving water, spring oak and cedar pollen loading phosphates into the pool, or a heavy storm that diluted your chlorine and dropped organic debris in at the same time.
What it costs
Priced by how far gone it is
We quote after we see the pool, because the price depends on size, how long it has been green, how much debris is in it, and whether your equipment is working. Light blooms are quick and cheap. A pool that has been sitting since last season is a different job, and we will tell you which one you have before we start.
Our Process
How we bring it back
Day 1, assess and clear
Full water test, baskets emptied, debris netted out, and every surface brushed. Brushing matters more than people expect, because it breaks the protective layer so chlorine can actually reach the algae. The pump goes to 24 hours a day and stays there.
Days 2 to 4, shock and filter
We drop pH, then shock after sunset so the sun does not destroy it before it finishes the job. We hold chlorine above 5 ppm, add algaecide after the shock, and clean the filter repeatedly as it loads up with dead algae.
Day 5, polish and rebalance
Clarifier for any remaining haze, a full chemical rebalance, and a final run of filtration. By the end you should be able to see the main drain clearly from the deck.

My Pool Helper is owner-operated by David. He learned pool care from the ground up in a family that has spent more than 30 years in the business, and built My Pool Helper on three rules he won’t bend on: show up every time, tell you the truth (no upsells), and sweat the small stuff — right down to a written water report after every visit.
David is a Certified Pool Operator (CPO), licensed and insured in Texas — so your home and your pool are in qualified hands.
We know Denton County pools inside and out
My Pool Helper is owner-operated and based right here in Denton County, so your pool is cared for around the realities of North Texas — not a generic checklist. Our tap water is classified “very hard” (about 15 grains per gallon, drawn from the Trinity Aquifer and Lewisville Lake), which scales tile, plaster, and salt cells fast. We check calcium hardness on every visit and balance for it, so the local water never quietly wears down your pool.
North Texas weather is just as demanding. Summers top 100°F and intense UV burns off chlorine and stabilizer within days — the reason weekly service beats bi-weekly here, and why we tune cyanuric acid and sanitizer for our exact climate. Then winter flips the script: a sudden hard freeze (like February 2021) can crack pumps, filters, and lines overnight. From Denton and Flower Mound to Argyle, Highland Village, and Lantana, it’s the local know-how that keeps pools clear all year.

Common Questions
Everything you need to know
How long until I can swim?
Do you have to drain my pool?
Rarely. Draining is a last resort here because our clay soil can let an empty shell float and crack, and a refill costs real money before any chemicals go in. The main reasons we would recommend it are cyanuric acid above 100 ppm, dissolved solids above 3,000 ppm, or algae embedded in the plaster surface.
Why does my pool keep turning green even after I treat it?
Four usual causes, and it is worth finding out which is yours: cyanuric acid too high so your chlorine cannot work at any reading, phosphates feeding the algae faster than chlorine can kill it, biofilm in the plumbing lines reseeding the pool, or a filter that is undersized or simply not running long enough.
Can I swim while it is being treated?
No. Chlorine runs far above normal levels during a recovery, and more importantly you cannot see the bottom of the pool.
Can I just do this myself with a bag of shock?
One bag of shock on a green pool is the most common mistake there is. A real recovery needs the pH dropped first, a large enough dose delivered after dark, chlorine held above 5 ppm for several days, and the filter cleaned repeatedly as it loads up. Most people who try it end up half treated with a filter full of algae.
Do I need ongoing service afterward?
Not required. But a recovered pool that goes back to the same routine tends to go green again, which is why most of our green to clean customers move onto weekly service afterward.
