Water Chemistry & Dosing
FC/CYA, pH, TA, CH, CSI, startup chemistry, scale control, and buying chemicals wisely.

CSI Water Balance: Scale Risk and Stability
Understand CSI as Poolometer's balance lens for scale and corrosion risk in outdoor residential pools.
Indoor vs Outdoor Pool Care
Adjust chemistry priorities for UV loss, debris, ventilation, humidity, and chloramine control based on where the pool lives.
New Plaster Startup
Protect fresh plaster during the first month with careful brushing, documented chemistry, and builder/manual alignment.
Pool Chemistry 101
Understand FC/CYA, pH, alkalinity, calcium, and CSI without turning pool care into folklore.
Pool Surfaces and Finish Care
Match stain, scale, startup, and calcium guidance to the actual surface instead of treating every pool like plaster.
Rain Dilution Calculator
Estimate how rainfall changes volume and why you still need to retest CYA, salt, and chlorine after a storm.
Scale Prevention Routine
Use CSI, brushing, and measured adjustments to stay ahead of scale on tile, heaters, and SWG cells.
Smart Shopping for Pool Chemicals
Buy commodity chemicals more carefully, read labels, and avoid paying premium pricing for repackaged basics.
Source Water and Refill Water
Test the water you are adding so recurring hardness, metals, and TDS problems stop feeling mysterious.
Source Water Pre-Treatment
Use hose-end filters, alternate fill sources, softened-water caveats, and repeat-fill strategy intentionally when refill water keeps reintroducing the same burden.
