Arcadia pools are large, heavily used and surrounded by old trees. That combination makes them among the most demanding water in the whole 91006 area — and the failures are predictable enough to plan around.
A big pool is not a small pool with more water in it. Chemical demand scales with gallons and brushing with surface, so a 35,000-gallon pool with a spa and a wide ledge is roughly two jobs. Add a summer of daily use — swimmers consume chlorine — and the water can read fine on Monday and be struggling by Friday.
Then the water itself. Fill water here is hard, evaporation off a large heated surface concentrates it, and calcium drops out onto the tile, the ledge and the inside of the salt cell. Scale here is not an occasional annoyance; it is the standing cost of owning the pool.
What goes wrong on Arcadia pools
- The chlorine smell that means too little chlorine
Heavy summer bather load produces chloramines, and chloramines are what people smell. A pool reading fine on total chlorine can be well short on free chlorine, so we read both every visit.
- Brown staining under the oaks
Mature oaks and sycamores drop tannin-rich leaf that stains plaster if it sits. Acorns and feathers — this is peafowl country near the Arboretum — block baskets, and a blocked basket is a pump running against resistance.
- Scale on the tile and inside the salt cell
Hard fill water, a big evaporating surface and a heated spa. On the tile it is visible; on the cell it is not, and a scaled cell under-produces chlorine long before it reports a fault. Salt system repair.
- A spa used all winter, drifting between visits
The smallest body of water on the property is the one that moves fastest. Heated, used, and topped up with hard water, an Arcadia spa needs the same attention as the pool in a fraction of the volume.
What we do for Arcadia pools
Weekly maintenance
Free and total chlorine both read, plus calcium hardness, TDS and the rest of the panel. Pool and spa on the same visit, brushing, all baskets, whole pad.
Acid wash
For plaster gone dull under years of scale and organic staining. Drained, washed at 50/50 acid to water, on a shell with at least half an inch of plaster left.
Equipment repair
Pumps, heaters, filters, salt generators, plumbing, lights and automation. We install Pentair and Jandy, which is what most large Arcadia pads run.
Green to clean
A big pool goes green slowly and comes back the same way. No draining, filter cleaned two or three times through the process, swimmable in about two days.
New plaster start-up
Seven days of active daily work, calcium hardness held at 200–400 ppm from day one. With water this hard, that first week decides the next decade.
How the Arcadia route runs
Fixed weekday, fixed route. It matters more here than most places: a large pool under trees is a debris job as much as a chemistry job, and the gap between visits decides how much leaf sinks and stains. One visit a week year round is standard; big pools with heavy summer use and a working spa are often better on two, the second landing three or four days after the first rather than the day before the weekend. Pre-party cleanings need 24 hours' notice.
We do not sell one-time routine cleanings. A pool that has been left gets a green-to-clean or an acid wash first, then joins the route.

Questions we get from Arcadia
Why does my pool smell of chlorine when it has chlorine in it?
That smell is chloramines, not chlorine — the by-product of chlorine that has already done its work. It is a sign of too little free chlorine for the load, not too much. A test that reads only total chlorine will miss it completely.
Do oak leaves really stain the plaster?
Yes. Tannins leach out of wet leaf and mark a light surface within days if the leaf is left sitting on the floor. Netting and vacuuming on a fixed weekly rhythm is what prevents it. Once the stain is in the plaster it is an acid wash question, not a cleaning question.
Should a large pool get two visits a week?
If it is in real use through summer and sits under trees, usually yes in the warm half of the year. The second visit buys debris removal and chlorine, not a second full chemical service. Many Arcadia properties run two in summer and one through winter.
Feathers and droppings keep ending up in the skimmer. What does that do?
Two things. Feathers pack a skimmer basket faster than leaf does, which starves the pump. Organic waste consumes chlorine, so demand rises in the same week the basket blocks. Both are handled by emptying baskets and holding free chlorine at target, not by special treatment.
