An underground pool can turn any backyard into a relaxing oasis. But to keep it looking great and safe to swim in, regular pool maintenance is a must. In this blog post, we’ll walk you through everything you need to know about underground pool maintenance—from weekly tasks to common problems and when to call in the pros.
Why Underground Pool Maintenance Matters
Maintaining your underground pool isn’t just about looks—it’s about keeping your pool safe, clean, and running properly. Regular maintenance helps:
-
Prevent algae and bacteria buildup
-
Extend the life of your pool equipment
-
Save you money on repairs
-
Keep your water clear and inviting
Weekly Pool Maintenance Checklist
1. Skim and Remove Debris
Use a pool skimmer to remove leaves, bugs, and other debris floating on the surface. This keeps the water clean and stops organic matter from clogging the filter.
2. Brush the Pool Walls
Algae can grow on the sides of your pool, especially in corners and shady spots. Brush the pool walls and floor weekly to prevent buildup.
3. Vacuum the Pool
Manual or automatic pool vacuums help remove dirt and particles from the bottom of your pool. Do this at least once a week.

4. Clean the Filter
Whether your pool has a cartridge, sand, or DE filter, it needs to be cleaned regularly to work properly. Check it weekly and clean or backwash as needed.
5. Test and Balance the Chemicals
Water chemistry is key to safe swimming. Use a test kit to check:
-
pH levels
-
Chlorine or sanitizer levels
-
Alkalinity
-
Calcium hardness
Make adjustments using the right pool chemicals.
6. Check the Water Level
The water level should stay about halfway up the skimmer opening. Too low and your pump could get damaged; too high and the skimmer won’t work right.
Common Underground Pool Problems (and How to Fix Them)
Green or Cloudy Water
Usually caused by algae or unbalanced chemicals. Shock the pool, clean the filter, and brush thoroughly.
Stains on Pool Walls
Metal or organic debris can cause staining. Use a stain remover specific to your pool type (vinyl, concrete, or fiberglass).
Pump or Filter Not Working
Could be a clog or air in the system. Turn everything off, check for blockages, and restart the system. If that doesn’t work, call a pro.
