Our pool technician will come to the pool every week, check and adjust the chemistry, check and, if needed, empty the skimmer and pump baskets, brush the water-line tile, skim the surface of the pool and vacuum the whole pool/spa/fountain. On a monthly basis (or more often if the pool dictates) they will clean your pool filter. At the end of their service they will leave you a card with your chemical readings, advice as to whether it is safe to swim and details of action that they wish you to take or concerns that they have about your pool equipment.
