How it works
ELP uses a Pseudomonas-selective chromogenic chemistry that responds specifically to Pseudomonas aeruginosa — the organism responsible for hot-tub folliculitis and many premise-plumbing biofilm risks. Sensitivity is 1 CFU/mL with a 48 hr ambient incubation.
Collect 1 mL sample from the pool / hot tub / splash-zone water
Incubate
Incubate 48 hr at 20-35°C (room temperature)
Read visible color change; positive flags Pseudomonas presence

Comparison
vs. traditional lab testing
Membrane filtration lab culture
Off-site, multi-day turnaround. Requires lab account, membrane filtration manifold, and qualified microbiology technician. Per-test cost from $40–$120 plus shipping.
On-site, same-day result
Single-organism specificity (vs broad-spectrum bacteria tests) at 1 CFU/mL — same sensitivity as a Pseudalert / cetrimide selective culture, faster and without lab plating.
