Questions
When should I winterize my pool in Boise?
In Boise, pool winterization typically occurs after Labor Day through October. Schedule before first hard freeze for proper system protection.
How often should I backwash my sand filter?
Backwash when filter pressure gauge rises 8-10 psi above clean filter reading. Regular monitoring maintains optimal filtration efficiency.
Do I need to add more chlorine during hot weather?
Test water weekly during summer heat. Chlorine demand increases with temperature and usage, requiring more frequent adjustments.
How often should I drain my hot tub?
Drain and refill spa water every 3-4 months depending on usage frequency and water balance maintenance practices.
Can I run my pool pump overnight?
Occasional overnight operation helps circulate chemicals but increases equipment wear. Run during peak sunlight hours for optimal chlorine efficiency.
What causes cloudy pool water after adding chlorine?
Cloudiness often indicates phosphate contamination, improper pH balance, or filtration issues. Bring water sample for free testing to identify specific cause.

I came in frustrated with my above ground pool filter and the lack of service from the manufacturer. By the time I left i had exactly what I needed and got my filter up and running within minutes. Such a great experience.
