WHY DRESHER POOLS NEED CONSISTENT MAINTENANCE
Haverford College Arboretum Makes Pool Maintenance in Ardmore a More Demanding Job
The Haverford College Arboretum was established in 1834 and covers over 200 acres directly adjacent to Ardmore’s residential neighborhoods. It is one of the oldest continuously maintained arboretums in Pennsylvania and one of the most biologically diverse collections of woody plants in the Philadelphia region.
The trees in the arboretum include mature specimens of oak, maple, beech, linden, and dozens of other species that have been growing for 150 or more years. These are not young suburban plantings. They are fully established biological systems producing pollen, organic debris, seed pods, and leaf material at the scale that only comes from a century and a half of continuous growth.
For pool owners in the residential streets immediately surrounding the arboretum along Lancaster Avenue, Cricket Avenue, Montgomery Avenue, and the neighborhoods running toward Haverford Road, the practical result is one of the highest ambient organic loads of any residential pool environment on the Main Line. Organic material from the arboretum enters pool water continuously through the growing season.
Each organic input event contributes to the pool’s phosphate load, and phosphates are the primary food source for algae. A pool in close proximity to the arboretum that is maintained with a standard weekly chemical routine not calibrated for elevated phosphate management will cycle through algae problems more frequently and with less warning than a pool in a more open, less organically rich environment.
