With Lange's weekly services, aquatic investigators will thoroughly test chemical balances, check seven separate measurements, and fine-tune as needed. Pole patrollers skim pools top to bottom, brushing walls and floors to ensure all debris is removed. At least every other week, filthy filters get cleaned out and grimy tile gets scrubbed to a twinkling sheen. Cleaners can vacuum, shock, and brush pools as needed, and also perform other chemical treatments. With Lange's Total Pool Care taking care of your personal mini ocean, pool owners have plenty of time to get back to playing Marco Polo, doing cannonballs, and inventing underwater chess.
