Yellow film. Daily skimming. Filter pressure climbing. Sound familiar?
North Texas brings its own variables: oak pollen for six weeks, calcium-rich source water, sub-freezing nights every winter, and summers that crank chemistry usage. The advice below is calibrated for those realities, not a generic national pool blog.
The 4-week plan
- Week 1: Pre-stage clarifier; increase brushing to 2× per week
- Week 2: Add phosphate remover; backwash if needed
- Week 3: Switch to enzyme treatments to clear oils + film
- Week 4: Deep filter clean once visible flow has dropped
Don't shock-then-vacuum every visit. You'll burn through chlorine and shorten your filter's life.
