What we've learned servicing pools here
The most overlooked factor in Toronto pool service is municipal water variability. Toronto's water profile shifts subtly across the year — slightly more chloramine in summer, occasional chlorine spikes after maintenance events, and seasonal pH variation. Pools topped up frequently with municipal water inherit these shifts, which is why even well-maintained pools sometimes drift unexpectedly. We track municipal water reports and adjust fill-water chemistry handling accordingly — most service companies treat municipal water as static, which it is not.
