Free Residential Pool Log Book Template
Keeping a pool log might sound like something only commercial pool operators need to do, but tracking your water chemistry and maintenance tasks is one of the best ways to keep your backyard pool crystal clear and avoid costly problems. A simple weekly record helps you spot trends, remember when you last added chemicals, and gives your pool service technician valuable information if you ever need professional help.

Why Keep a Pool Log?
Most pool problems don't happen overnight. Algae blooms, cloudy water, and equipment failures are usually the result of gradual changes that could have been caught early with regular testing and record-keeping.
Spot Trends Early
See patterns in your water chemistry before they become problems. Consistently dropping pH? Rising cyanuric acid? Your log will show you.
Save Money
Prevent expensive chemical corrections and equipment repairs by catching issues early. Know exactly what you added and when.
Remember What Worked
When your pool looks perfect, your log shows exactly what you did. When something goes wrong, you can trace back to find the cause.
Help Your Pool Pro
If you ever need to call a pool service, your log gives them valuable history to diagnose problems faster.
What to Track
You don't need to test every day like a commercial pool. For most residential pools, weekly testing is enough to maintain good water quality. Here's what to record:
Weekly Water Tests
- Free chlorine (2-4 ppm ideal)
- pH level (7.4-7.6 ideal)
- Total alkalinity (80-120 ppm)
- Cyanuric acid (30-50 ppm)
Monthly Tests
- Calcium hardness (200-400 ppm)
- Total dissolved solids
- Salt level (salt pools)
- Phosphate level
Chemical Additions
- Chlorine/shock amount
- Acid or soda ash
- Algaecide treatments
- Specialty chemicals
Maintenance Tasks
- Filter cleaning/backwash
- Skimmer basket cleaning
- Pump basket cleaning
- Brushing and vacuuming

Tips for Consistent Pool Care
1. Pick a Testing Day
Choose the same day each week for testing. Many pool owners test on Saturday or Sunday morning when they have time to add chemicals if needed.
2. Test Before Swimming
Test your water before anyone swims, not after. Swimmers add oils, sunscreen, and other contaminants that can temporarily affect readings.
3. Keep Chemicals Organized
Store your chemicals in a cool, dry place and keep your log book nearby. This makes it easy to record additions right after you make them.
4. Note the Weather
Rain, extreme heat, and heavy winds all affect your pool chemistry. Recording weather conditions helps you understand why readings change week to week.
5. Don't Skip Weeks
Even if your pool looks fine, test and record anyway. The most valuable part of a log is having consistent data over time.
