Keeping a pool clean in Sanur is less about fancy gadgets and more about small daily habits. Sea air, construction dust, and the wet season all work against you, so a simple routine keeps the water clear and your family safe. Here is what to do each day, week, month, and how to handle the rainy months without stress.
Daily Habits (Five Minutes Is Enough)
Grab a leaf net and skim the surface before it gets hot. In Sanur the breeze off the beach carries sand, tiny insects, and occasional palm fronds that settle overnight. A two-minute pass keeps them from sinking into the filter media.
Glance at the water level – it should sit mid-way on the skimmer opening. If it has dropped noticeably, top up with PDAM or well water rather than letting the pump run dry.
Do a quick visual check: any green tinge near the tile line, a cloudy patch, or an oily film? Note it down and address it the same evening before algae gets a foothold.
- Skim leaves, insects, and sand
- Check water level at the skimmer
- Look for cloudiness, oil film, or early algae
Weekly Routine (About 30–40 Minutes)
Brush the walls, floor, and especially the corners where water circulation is weakest. Algae in Bali starts as a faint green sheen; catching it while you brush means you never need a shock dose.
Vacuum the bottom, then empty and rinse the skimmer baskets and the pre-filter strainer basket inside the pump housing. Clogged baskets are the number-one reason pumps lose pressure here.
Test pH and free chlorine with liquid test strips or a drop kit. Write the numbers down so you can spot trends over weeks.
If your pool uses a cartridge filter, remove the cartridges, hose them off from the outside in, and let them dry before putting them back. Sand filters get a short backwash cycle instead.
- Brush all surfaces, focus on corners
- Vacuum the floor
- Clean skimmer baskets and pre-filter strainer
- Test pH and free chlorine
- Rinse cartridge / backwash sand filter
If something looks off – cloudy water, a pump that will not start, an odd chemical smell – snap a quick photo and send it over WhatsApp; we will walk you through the next step.
Monthly Deep Check
Pull the filter cartridges out completely and soak them overnight in a dedicated filter-cleaner solution (available at any hardware shop in Sanur). This removes oils that hosing alone cannot shift.
Walk the pipework: check every union, valve, and the pump seal for weeping. A slow drip behind the pump housing will rot the wooden deck of older villas if left unattended.
Inspect the return jets for calcium scale or blockages. If water comes out in a weak stream, the jet is partially clogged – clear it with a thin rod or vinegar soak.
Top up your chemical stock while you remember. Running out mid-week during the rainy season means a green pool by Friday.
- Soak filter cartridges in cleaner
- Check pipes, valves, pump seal for leaks
- Clear return jets of scale
- Restock chemicals
Pool Chemistry Basics
Aim for pH between 7.2 and 7.6. Below that, chlorine becomes aggressive to skin; above it, chlorine stops working effectively. Adjust slowly – add acid or soda ash in small increments and re-test after an hour.
Keep free chlorine between 1 and 3 ppm. In Bali's heat, evaporation and UV burn through chlorine faster than in temperate climates, so test twice a day during summer months.
Never mix chlorine granules or liquid with acid, other algaecides, or any product you have not read the label on. The reaction can release toxic gas. If you ever smell sharp fumes while dosing, step back outside, ventilate, and call a professional before touching anything else.
One local nuance: well water in parts of Sanur carries more iron and manganese than PDAM mains. If your water turns yellow-brown after a refill, ask about adding a metal-sequestrant alongside your regular treatment rather than simply raising chlorine.
- pH target: 7.2–7.6
- Free chlorine target: 1–3 ppm
- NEVER mix chlorine with acid or other chemicals – stop and call a pro if fumes appear
- Well water may need extra metal sequestration
Equipment You Should Know
Pump: listen for grinding or whining that was not there last month. Watch the pressure gauge; a steady rise means the filter is clogging. If the pump trips its thermal cut-out repeatedly, switch it off and let it cool – do not keep restarting it.
Heater (if fitted): descale the heat exchanger every few months, especially if you use well water. A blocked heater will overheat and trip safety switches.
Salt-chlorinator cell: inspect the titanium plates quarterly for white crust. Rinse gently; heavy scaling shortens cell life dramatically in humid air.
Electrical safety: never open the pump junction box, touch wiring, or reset a tripped RCD while your hands are wet or the area is splashed. Pool electrics near standing water are a genuine shock hazard. Switch everything off at the main isolator and call a licensed electrician or pool technician to investigate.
- Listen for abnormal pump noise; watch pressure gauge
- Descale heater periodically
- Inspect salt-cell plates for scale
- Never work on pool electrics while wet – isolate power and call a professional
Surviving the Rainy Season (November–March)
Heavy downpours dilute your chlorine, wash organic matter into the pool, and can push the pH up as rainwater carries dissolved CO₂ out of solution. Expect to re-balance within 24 hours of a big storm.
After a storm, skim aggressively, brush the tile line, and test before anyone swims. Algae blooms that look impossible overnight are almost always post-rain events in Sanur villas.
Check overflow drains and the skimmer channel for silt and leaf pulp. A blocked overflow will back-flood the pool room during a monsoon shower.
The combination of sea spray, high humidity, and constant moisture accelerates corrosion on stainless fittings, ladders, and metal pool furniture. Wipe them dry after heavy rain and apply a thin coat of anti-corrosion oil on exposed bolts twice a month.
- Re-test and rebalance within 24 h of heavy rain
- Skim and brush immediately after storms
- Clear overflow drains of silt
- Wipe and oil metal fittings to fight corrosion
Questions
How often should I really test my pool water in Bali?
At minimum once a day during hot months and after any heavy rain. In practice, most villa owners here test every morning with liquid strips – it takes under two minutes and catches drift before it becomes a green-pool emergency.
Can I just buy whatever chemicals are at the local hardware shop?
You can pick up pH adjusters, chlorine, and algaecide from shops along Jl. Raya Sanur or in the small markets, but make sure the products are compatible and that you follow the label dosing rates. If you are unsure which product does what, send a photo of the bottle on WhatsApp and we will tell you whether it fits your routine.
My pool turned green overnight. What do I do first?
Do not panic-dose. Test pH and free chlorine first; if pH is above 8, bring it down before adding more chlorine because high pH neutralises it. Then shock-treat according to the product instructions, run the pump continuously for 24 hours, and vacuum. If it is still cloudy after 48 hours, photograph the water and the filter setup and send them over for a second look.
