Introduction

Keeping a pool clear isn't hard, but it is relentless, and that's what trips people up. The same short list of jobs needs doing every week, and skipping it for a fortnight is usually how a clear pool turns green.

This checklist walks through everything a pool needs weekly, in the order that makes it quickest, plus the target numbers to aim for and a few habits that make the whole thing easier.

Key Takeaways

• The full routine takes about 60 minutes weekly

• Always clean your pool before you test the water

• Balanced water is what keeps the pool clear

• Empty your pool baskets so the pump isn't straining

Quick Comparison: Your Weekly Targets

Pull your water sample about 18 inches down and away from the return jets, so you're testing the real pool, not fresh return water.

1. Empty the Baskets First

Start here, because clogged baskets choke your circulation and make everything else less effective. A skimmer packed with leaves means the pump is straining all week.

• Empty the skimmer basket

• Empty the pump strainer basket

• Rinse out any built-up debris

• Check for cracks while they're out

A pump fighting against full baskets works harder, costs more to run, and wears out sooner. So this 60-second job protects your most expensive equipment.

2. Skim and Brush the Surfaces

Next, skim the surface and brush the walls, before anything settles or takes hold. Leaves left floating sink and stain, and algae starts as an invisible film long before you can see green.

• Skim the surface with a leaf net

• Brush walls, steps and the waterline

• Focus on corners and behind ladders

• Brush toward the main drain

Those low-circulation spots behind steps and ladders are where algae always starts, because the sanitizer barely reaches them. So that's exactly where the brush matters most.

3. Vacuum the Floor

Brushing loosens debris, but vacuuming is what actually removes it. Skip this and fine dirt just resettles into a gritty layer on the floor.

• Vacuum in slow, overlapping passes

• Go slow to avoid clouding the water

• Cover the whole floor, not just the middle

• A robotic cleaner can do this for you

Rushing the vacuum stirs everything back up, which undoes the work. Slow passes are the difference between clear water and a cloudy afternoon.

4. Test Before You Add Anything

Now test the water, and do it before dosing anything, because adding chemicals blind is how pools swing from one problem to another. Testing first tells you what the water actually needs.

• Test pH, chlorine and alkalinity weekly

• Sample 18 inches down, away from jets

• Use fresh strips or a drop kit

• Test twice a week in peak summer heat

As Certified Pool Operators, this is the step we'd never skip, because every other decision depends on it. A clear-looking pool can still be badly out of balance underneath.

5. Balance the Water, Low and Slow

Once you know your numbers, adjust them carefully. The mistake is dumping in a big correction, overshooting, and chasing the balance back the other way all week.

• Add small amounts, then let it circulate

• Retest before adding any more

• Never mix chemicals together directly

• Add one chemical at a time

Balanced water isn't just about clarity. It's what stops the water quietly corroding your surfaces and equipment from the inside out.

6. Check Chlorine and Refill the Feeder

With the water balanced, make sure your sanitizer will hold all week. Chlorine gets consumed constantly by sun, swimmers and debris, so the level needs topping back up.

• Check free chlorine is 1 to 3 ppm

• Refill tablets in your feeder or chlorinator

• Never put tablets in the skimmer basket

• Buy fresh chlorine, it weakens in storage

Tablets in the skimmer send acidic water straight through your pump and heater when the system's off. It's one of the most common causes of premature equipment damage we see across our 150+ pools.

7. Check the Filter Pressure

Your filter is the engine behind clear water, and the pressure gauge tells you when it needs attention. A clogged filter slows circulation and clouds the whole pool.

• Note the pressure on the gauge

• Backwash or rinse at 8 to 10 psi above clean

• Rinse cartridge filters with a hose

• Run the pump 8 to 12 hours daily

That 8 to 10 psi rise above the clean baseline is your trigger to clean it. Cleaning too often actually reduces filtration, so wait for the number rather than doing it on a fixed day.

8. Check the Water Level

Finally, check the water level, since it affects both skimming and your pump. The sweet spot is the middle of the skimmer opening.

• Keep water at the skimmer's midpoint

• Top up if it drops below halfway

• Too low can burn out the pump

• Too high and the skimmer stops working

If you're topping up far more than a hot week would explain, that's worth investigating. Persistent water loss often points to a leak rather than evaporation.

When Should I Shock the Pool?

Shocking isn't a weekly job, but it belongs on the checklist for when the water needs a reset. Do it after anything that overwhelms your normal chlorine.

• After heavy rain or a storm

• After a party or heavy swimmer load

• When the water looks dull or cloudy

• Always at night, so sun doesn't burn it off

The Bottom Line

A good weekly routine is about an hour: empty the baskets, skim and brush, vacuum, then test and balance the water. Stay on top of that and the big problems mostly never show up.
