When to start preparing?
The best time to open your pool is early spring, when temperatures rise above +15°C. Don’t wait for scorching heat: the sooner you begin cleaning, the easier it is to prevent algae growth. If the winter was mild, check the pool as early as March—ice or debris might have damaged the liner.
Step 1: Remove the cover and compensators
✔ Take off the winter cover, clean it of dirt, and dry it before storing.
✔ Remove compensators if they were installed.
Important! If water remains in the pool, clear debris from the cover before removing it to avoid dumping it into the basin.
Step 2: Clear debris and clean the liner
✔ Use a net to collect leaves, twigs, and other debris from the surface.
✔ Add water up to the skimmer level.
✔ Scrub the bottom and walls to remove buildup using a brush or pool vacuum.
✔ A robotic vacuum can both clean the liner and filter the water.
Step 3: Connect and test equipment
✔ Set up the filter, pump, disinfection systems, and heater.
✔ Check the seals and electrical insulation for leaks.
✔ Ensure the filtration system operates without issues.
✔ For sand filters, inspect the fill level and replace it if needed.
✔ Install add-on equipment: ladders, handrails, diving boards.
Step 4: Start filtration and check system performance
✔ Turn on the filtration and confirm the water circulation runs smoothly.
✔ Test the heater, if you have one.
✔ Ensure chemical dosing equipment is properly connected.
Step 5: Test and treat the water
✔ Use test strips to measure pH (ideal range: 7.2–7.4) and chlorine levels (0.3–0.6 mg/L).
✔ Add pH adjusters if necessary.
✔ Apply shock chlorine for disinfection.
✔ Green water after winter is common—add algaecide to eliminate algae and prevent regrowth.
✔ Stir the water with a net and run the pump for 4–6 hours.
Important! Always follow the dosage instructions on chemical packaging.
Step 6: Final inspection
✔ After 24 hours, recheck pH and chlorine levels.
✔ Examine the filter to ensure it’s clean.
✔ The water should be clear, free of cloudiness or odors.
Your pool is now fully ready for the season after winter!
Tips for an easy start
✔ Don’t leave the pool uncovered during winter—it’ll make spring cleaning harder.
✔ If the water is green after winter, use a shock dose of chlorine before cleaning.
✔ Store chemicals in a dry place to maintain their effectiveness.
✔ Regularly check the filter—a clean system saves time and effort.
Cleaning a pool after winter: tips for frame models
How to clean a pool after winter? If a frame pool stayed outside during the cold months, take extra steps:
✔ Inspect the frame and PVC walls for damage.
✔ Check the supports and fastenings for stability.
✔ Brush the walls to remove buildup and dirt.

Now you understand what cleaning a garden pool after winter involves and how to prepare it for the season. This process takes 1–2 days, but proper care will keep troubles at bay all summer long!
