How often should I clean my pool?
Empty the skimmer and pump baskets every day or two, test chlorine and pH at least a few times a week, brush and vacuum weekly, and test alkalinity, hardness and stabilizer weekly. Backwash or clean the filter when its gauge rises, not on a calendar. Public pools are held to a stricter daily routine; use it as the ceiling.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Empty the baskets
Empty the skimmer basket and the pump's hair and lint basket every day or two in swimming season; public pools do it daily.[1]
Step 2: Test chlorine and pH
Test free chlorine and pH at least a few times a week, and after storms or heavy use, aiming for free chlorine of 1.0 to 3.0 ppm and pH of 7.2 to 7.8.[2]
Step 3: Brush and vacuum weekly
Brush the walls, steps and floor and vacuum the settled debris once a week, or more often after leaves or a storm.
Step 4: Wipe the waterline
Clean the scum line from the tiles or liner at the waterline when you brush.
Step 5: Run the weekly tests
Once a week, test total alkalinity, calcium hardness and cyanuric acid (stabilizer).[1]
Step 6: Watch the filter gauge
Note the gauge reading right after cleaning the filter, and clean or backwash it when the pressure has climbed as its manual specifies.
Step 7: Keep a log
Write down readings and what you added so a pattern shows up before a problem does.
A schedule that works
Clean the baskets every day or two in season, test chlorine and pH a few times a week, brush and vacuum once a week, and run the fuller weekly tests on the same day. Clean or backwash the filter by its gauge. That routine is what keeps a pool from turning green or cloudy.
Public pools set the upper limit. The Portsmouth Health Department's operator guide describes what an operator does every day; a home pool needs less because fewer people use it, but the same tasks apply.
Daily or every other day
Baskets. The skimmer basket should be cleaned out daily to allow for maximum flow through the skimmer.[1] The same goes for the pump: the pump's hair and lint catcher has a removable basket that should be cleaned daily.[1] A full basket starves the pump and the filter, and water that does not circulate does not stay clear. Switch the pump off before opening the pump lid.
Net the surface. Skim leaves and insects before they sink and break down.
A quick look. Check the water level, the gauge, and whether the main drain is clearly visible.
Several times a week
Chlorine and pH. Virginia's water quality standard for pools keeps free chlorine between 1.0 and 3.0 ppm and pH between 7.2 and 7.8.[2] It is written for regulated pools, but it is a sensible target at home. The guide says chlorine and pH levels should be checked every day before the pool is opened and every two hours after that.[1] You will not test every two hours at home, but the reasoning carries over: the more often pool water is tested, the more quickly, safely and easily improper levels can be corrected.[1] Test more often after storms, heat waves and parties.
Weekly
Brush and vacuum. The guide's daily list for a public pool includes vacuuming and brushing the pool walls and bottom, backwashing the filter if necessary, cleaning the skimmer baskets, and testing the water and recording the results.[1] At home, weekly is the usual rhythm for brushing and vacuuming, with extra passes after leaves or a storm. The guide also lists cleaning the grease line from the pool wall tiles among the daily items.[1] At home, wiping the waterline when you brush is enough.
Fuller water tests. Total alkalinity, calcium hardness and stabilizer (cyanuric acid) must be checked weekly, the guide says.[1] These readings move slowly, but they decide whether pH holds steady and chlorine works; how to balance pool chemicals explains the targets.
The filter: by gauge, not by date
There is no calendar answer for the filter. The guide says the filter should be backwashed when the difference between the influent and effluent gauge readings is 7 to 10 psi for a rapid sand filter,[1] and that bather load, location of the pool and algae growth also influence the length of time between filter runs.[1] Cartridge filters have their own routine; see how to clean a pool cartridge filter. Always follow your filter's manual first.
Keep a log
Weekly, monthly or seasonal maintenance schedules should be drawn up and posted as permanent records, the guide advises.[1] A notebook or phone note on your readings and what you added is enough. When the water turns, the log tells you what changed. If it does turn, why pool water gets cloudy walks through the causes.
Stop and call a pro if
- Readings will not stay in range even though you test and adjust on schedule. The cause may be a failing filter, a circulation problem or a source-water issue.
- The pump loses prime, leaks, makes a grinding noise or trips a breaker. Pump, plumbing and electrical faults are a job for a professional.
- Anything electrical or gas is involved, such as a light, heater or automation panel. Do not open or rewire them yourself.
- The repair would cost $1,000 or more. If the work you are considering is valued at $1,000 or more, a valid Virginia contractor's license is required.[3]
- You cannot keep up the routine. A service handles the weekly visit; see below.

Common questions
- Can I clean my pool only once a week?
- Many owners do, and it works in cool weather with a cover or little debris. In summer, a once-a-week visit usually leaves baskets overflowing and chlorine untested for days. A quick basket check and a chlorine and pH test midweek costs a few minutes and prevents most green and cloudy pools.
- How often should I test pool water?
- More often than most owners think. The Portsmouth Health Department's guide says the more often water is tested, the more quickly, safely and easily improper levels can be corrected. A public pool tests every two hours while open; at home, a few times a week plus after rain, storms and heavy swimming is a practical floor.
- How often should I backwash my filter?
- By the gauge, not the calendar. For a rapid sand filter the guide's rule of thumb is when the difference between the influent and effluent readings reaches 7 to 10 psi. Bather load, location and algae growth change how fast that happens, and your filter's manual comes first.
- Do I still need to clean a pool I rarely swim in?
- Yes. Debris, sun and warm weather still feed algae, so baskets, chlorine and pH need the same attention whether or not anyone swims. A pool in the off season needs far less, but see the guide to closing a pool.
- Is it worth hiring a pool service for the routine?
- If the weekly routine keeps slipping, yes. See what a service does each visit and what weekly service costs in Virginia through the links below, then compare against the time you spend.
