Back/First 30 Days - Establishing Your Baseline

First 30 Days - Establishing Your Baseline

Build a reliable baseline chemistry profile and learn your pool's behavior in the critical first month of ownership.

When to use: Just inherited a pool or completed startup and need to establish consistent chemistry patterns before problems arise.

Week 1: Daily Testing - Build Confidence & Find Patterns

Week 1

Your first week is about repetition and pattern recognition. Test daily to see how your pool behaves.

1 / 9

Day 1-7: Test FC and pH every single day, same time if possible (morning recommended)

Day 3: Run your FIRST full panel test (FC, pH, TA, CH, CYA, salt if applicable)

Day 7: Run SECOND full panel test - compare to Day 3 to verify CYA stability

Record everything: date, time, readings, weather, pool usage, chemical additions

Track FC drop: How much does FC decrease in 24 hours? This is your consumption baseline

Note pH drift: Does pH rise or fall? Most pools drift up due to aeration

Watch for patterns: Rain impact? Party day usage? Equipment runtime changes?

💡 Pro Tips

• Don't adjust anything yet! Just observe and learn your pool's natural behavior

• If CYA differs between Day 3 and Day 7, retest carefully - it should be stable

• Normal FC consumption is 1-3 ppm per day in summer, less in winter

• pH typically drifts up 0.1-0.3 per week - this is normal aeration

⚠️ Important Warnings

• If FC drops more than 5 ppm overnight, you have algae or contamination - run OCLT test immediately

• If CYA changes significantly (>10 ppm) between tests, you made a testing error - redo it

Checklist

  1. 1Week 1: Test daily (FC, pH) to understand consumption patterns and establish testing confidence.
  2. 2Week 1: Complete full panel (FC, pH, TA, CH, CYA, salt) on days 3 and 7 - verify CYA is stable.
  3. 3Week 2: Test FC/pH every other day, track patterns (when does FC drop? by how much?).
  4. 4Week 2: Perform OCLT (overnight chlorine loss test) to verify no hidden demand.
  5. 5Week 3: Reduce to 2-3x per week testing, compare results to establish your 'normal' ranges.
  6. 6Week 3: Document your weekly chlorine consumption - this is your baseline for detecting problems early.
  7. 7Week 4: Run full panel again, compare to Week 1 readings - verify stability in all parameters.
  8. 8Week 4: Calculate your pool's weekly chemical budget (bleach, acid, etc.) based on observed consumption.
  9. 9Document equipment runtime, weather impact, and usage patterns that affect chemistry.
  10. 10Create your personalized testing schedule based on observed stability (some pools need more attention).
  11. 11Know when to break the routine - post-rain, post-party, seasonal transitions.
