Pool Water Chemistry Tracking
Log pH, chlorine, alkalinity, calcium hardness, CYA, and salt, and see at a glance whether your water is balanced, drifting, or out of range.
A single test reading tells you today. A history tells you what your pool is actually doing. Skimmer turns every water test into a tracked, chartable record so you catch a slow drift before it becomes an algae bloom or a corrosive-water problem.
Inside the feature
Every parameter that matters, in one entry
Record pH, free chlorine, total alkalinity, calcium hardness, cyanuric acid, and salt together, the full set your pool's balance actually depends on.
Balanced, drifting, or out of range, automatically
Skimmer flags each reading against a healthy target range so you don't have to memorize what a normal number looks like.
Trends, not just today's snapshot
See how a parameter has moved over weeks and seasons, so a quietly-climbing alkalinity is visible long before it causes trouble.
Backfill past readings
Log a test with any past date to bring your notebook or spreadsheet history into one place.
