Indoor vs Outdoor Pool Care
UV loss, ventilation, covers, and chloramine behavior make indoor and outdoor pools behave like different systems.
- UV loss, ventilation, covers, and chloramine behavior make indoor and outdoor pools behave like different systems.
- FC and CC levels
- CYA level
- Pool location (indoor/outdoor)
- Do not treat indoor and outdoor pools with the same chemical habits
- Do not ignore ventilation as a root cause of indoor chloramine problems
Identify whether your pool is indoor or outdoor — UV loss and chloramine behavior require different operating strategies.
- ✕Do not treat indoor and outdoor pools with the same chemical habits
- ✕Do not ignore ventilation as a root cause of indoor chloramine problems
FC and CC levels / CYA level / Pool location (indoor/outdoor)
Outdoor pools: manage sunlight and debris
Outdoor pools lose chlorine to UV and collect organic load from the environment.
Indoor pools: manage air and chloramines
An indoor pool is also an air-handling problem.
Adjust testing priorities by environment
The same test kit can be used differently depending on where the pool lives.
