SLAM: Shock Level And Maintain
A residential algae-remediation workflow that uses repeated testing, brushing, and filtration instead of one-time 'shock' folklore.

Residential workflow, not universal code
Poolometer treats SLAM as a residential remediation model layered on top of accurate testing. It is not a public-pool code requirement and it should not replace local health rules, manufacturer limits, or chemistry testing.
- Use a current, accurate CYA reading before trusting any SLAM target.
- Use FAS-DPD chlorine testing. Test strips are not strong enough for this job.
Personalized target
With CYA at 30 ppm and current FC at 0 ppm, this residential workflow points to about 12 ppm FC.
Confirm that SLAM is actually the right tool
SLAM is for algae or persistent organic contamination, not every cloudy-water event.
Prepare the pool and your test workflow
Good data and good circulation matter more than dumping product fast.
Raise FC to the residential SLAM target
Raise FC from 0 ppm toward about 12 ppm, then verify with a retest after circulation.
Maintain, brush, and filter
The 'maintain' part is what makes SLAM work.
Use strict exit criteria
Do not stop because the pool merely looks better.
Return to normal operation carefully
After SLAM, transition back to your ordinary operating target rather than swinging chemistry again.
Questions?
When should I not start SLAM?
"Do not start with unknown CYA, obviously broken circulation, or a problem that is clearly mechanical rather than biological."
Why is the target tied to CYA?
"Poolometer uses the common residential FC/CYA model for algae remediation. Higher stabilizer generally means you need a higher FC target to get the same practical effect."
