Filtration parts and phosphate treatments stocked for Tewantin pool owners at Billabong Pool Service & Supply

Your Pool Supply Shop for Tewantin

Noosa Shire, QLD

Older pools, bigger backyards, and a great deal of leaf

Parts for equipment that predates its owner, and chemistry for water that is fighting a tree canopy

Tewantin is the everyday-residential end of Noosa Shire, and the census says so plainly: 11,164 residents — the largest of the four suburbs we supply — with 82.2% of occupied dwellings separate houses and only 7.3% of private dwellings unoccupied, the lowest share in the pack by a wide margin. These are pools in permanently lived-in houses on detached blocks. They are used all year, maintained by their owners, and most of them are fighting leaf rather than bather load.

Ask a Tewantin pool owner what their pool needs and the answer is rarely "more chlorine". It is leaves.

Organic matter that falls into a pool feeds algae, stains surfaces, blocks skimmers and consumes free chlorine long before UV gets to it. Dose against that without dealing with the load itself and you spend the season dosing.

Local water knowledge

What your pool needs here

At the 2021 Census, 82.2% of Tewantin's occupied dwellings were separate houses — the highest share of the four suburbs in this pack, against 56.9% at Sunshine Beach — and just 7.3% of private dwellings were unoccupied, against 37.6% at Noosa Heads. Median household income was $1,263 a week, the lowest of the four.

Read together, that describes owner-maintained pools at permanently occupied houses, on a budget that makes a repair genuinely preferable to a replacement. It is the opposite of the beachside pattern, where the pool has to be presentable for someone else on a fixed date.

A lot of these pools were also inherited rather than chosen. People buy an established house on a decent block and the pool comes with it — often with no manual, no service history, and an equipment pad nobody can identify. The first useful thing a pool shop can do in that situation is work out what you actually own, because the two expensive mistakes we see most both start there: replacing a whole system when a seal kit would do, and pouring chlorine into a pool whose real problem is a failed filter.

What brings people in

The problems behind the purchase

The challenge

Algae that keeps coming back on textbook chlorine

Why it happens

Decomposing leaf matter releases phosphate, and phosphate feeds algae faster than a normal residual knocks it back.

Why it matters

You dose constantly, never get ahead, and conclude the chlorine is not working when the food source is the problem.

How we help

Ask for a phosphate test. Treat the phosphate, clean or replace the filter element, then rebalance — most pools under canopy settle once the food is gone.

The challenge

Topping up from a tank or bore

Why it happens

Properties on the rural-residential fringe often top up from rainwater rather than town supply.

Why it matters

That water is typically low in calcium, and low calcium hardness in a concrete, plaster or pebble pool lets the water pull calcium out of the surface — etching and roughness over time.

How we help

Tell us what you top up with and we will test hardness and set a correction before the next top-up, not after the surface has gone.

The challenge

An equipment pad nobody can name

Why it happens

Pools change hands with the house; manuals and service records almost never do.

Why it matters

You cannot buy the right part for a system you cannot identify, and guessing costs trips and money.

How we help

Photograph the pump badge, the filter label, the chlorinator box and the plumbing at the pad. We can identify most of what is installed around Noosa from those, and tell you what is still supported.

The challenge

Shade that holds algae even when the reading looks fine

Why it happens

Part-day sun keeps a pool several degrees cooler and slower to dry, and damp corners stay damp.

Why it matters

Waterline and corner algae persist on a pool whose numbers look acceptable, so owners stop trusting the test.

How we help

We treat it as a circulation, brushing and filtration question first, and stock the covers and larger-capacity cleaners that cut the load at source.

Our pool supply range

What is on the shelves

Chemicals for organic load

Beyond the basics — phosphate remover, clarifier, flocculant, algaecide and enzyme treatments for pools sitting under a heavy canopy.

The products that matter when leaf and pollen drop is constant and chlorine keeps disappearing.

See what we stock

In-store water testing

A full bench profile including phosphate and calcium hardness, not just chlorine and pH, with the dosing order written down.

Every sample from a tank-topped or tree-shaded pool should have hardness and phosphate on it. Ask for both.

Bring a sample in

Filtration parts and pump repairs

Cartridges, filter media, baskets, seal kits and replacement pumps for older installs where flow has quietly dropped off.

Suits an inherited pool where nobody knows when the media was last changed.

Pool repairs

Robotic cleaners for leafy pools

Dolphin units with large-capacity filter baskets that cope with volume instead of clogging on the first pass.

Genuinely useful on a block where hand-vacuuming after a windy week is most of the weekend.

See the range

Pool heating for shaded pools

Shaded, tree-lined pools run colder than open ones and lose the shoulder seasons. Heat pumps suit these sites better than solar where roof exposure is limited.

We assess the site before recommending. A solar system under canopy is money spent on the wrong problem.

About pool heating

Covers, leaf gear and handrails

Solar blankets, rollers, leaf rakes, skimmer socks, brushes and handrails.

A cover is the highest-value purchase for a pool under trees — it stops most of the debris before it ever reaches the filter.

Why owners come back

Billabong Pool Service & Supply publishes ABN 63 010 047 239 and QBCC Licence No. 69021 in its own site footer. The Noosa shop is at 20 Rene Street, Noosaville QLD 4566 on 07 5449 7855, trading Monday to Friday 8:00am–4:30pm and Saturday 8:00am–12:00pm — a short drive from Tewantin via Cooroy Noosa Road or Hilton Terrace. There is no Billabong shopfront in Tewantin; the suburb is served from Noosaville. Billabong does not issue pool safety certificates and does not perform pool safety inspections — that is a licensed pool safety inspector's work.

Frequently asked questions

My pool is under trees and keeps going green. Is more chlorine the answer?

Usually not on its own. Decomposing leaves release phosphate, which feeds algae faster than chlorine can knock it back, so you dose constantly and never get ahead. Ask for a phosphate test, treat the phosphate, clean or replace the filter element, then rebalance. Most pools under canopy stabilise once the food source is removed.

I top up from a rainwater tank. Does that matter?

It does, and it is commonly missed. Tank and bore water is typically low in calcium, and low calcium hardness in a concrete, plaster or pebble pool lets the water leach calcium out of the surface, causing etching and roughness over time. Mention it when you come in and we will test hardness and set a correction before you top up again.

I have just bought a house with an old pool and do not know what any of it is.

Very common here. Photograph the pump badge, the filter label, the chlorinator box and the plumbing at the equipment pad, then bring the photos in. We can usually identify the system, tell you which parts are still available, and give you a short list of what to check first. Bring a water sample the same visit.

Is it worth repairing an older pump, or should I replace it?

It depends on the fault and the age. Seals, bearings and impellers are often worth replacing on an otherwise sound unit; a cracked housing or a motor that has already been rewound generally is not. We will also show you the running-cost difference against a variable-speed pump, since an older single-speed unit on long timer runs is frequently the largest power draw on the property.

How far is the shop from Tewantin?

20 Rene Street, Noosaville — a short drive via Cooroy Noosa Road or Hilton Terrace. There is no separate Tewantin shopfront; the suburb is served from Noosaville, where the stock and the service vans are. Call 07 5449 7855 first and we will confirm the part is on the shelf.

Can someone come out instead of me doing it myself?

Yes. A big block with heavy leaf drop is a good fit for scheduled visits, because the workload is seasonal rather than steady. Billabong runs regular pool maintenance, one-off cleaning and repairs throughout the area.

What is the single best thing I can buy for a pool under trees?

A cover, in most cases. It stops the majority of the debris before it reaches the water, which reduces the phosphate load, the filter workload and the brushing — three problems for one purchase. A larger-capacity robotic cleaner is the next one, for what still gets in.

Next step

Bring a water sample and the part that failed, and we will test, match and explain in one visit. Call 07 5449 7855 first and we will confirm it is on the shelf rather than have you make the trip twice.
