A: Over 30 years of proven performance has shown that the Sustain 3-Part System provides you with an effective and easy-to-use pool care routine. The use of other chlorine products often results in too little or too much chlorine. Sustain, The Intelligent Pool Care System, is formulated and designed to deliver chlorine more evenly than conventional pool care chemical systems. Also, as part of this System, Sustain Summer Shield is the brains of the program. This product actually holds backup chlorine in reserve, and only releases it when it senses your pool's level of chlorine protection (against algae and bacteria growth) has been depleted.
A:The Association of Pool & Spa Professionals (APSP) sets guidelines for pump and filter sizing that allow circulation flow to achieve at least two water turnovers per day. Operating your pump for 12 hours per day will ensure one turnover. Good circulation is necessary for filtration and dispersing the sanitizing chemicals throughout the pool water. Note: Set the return jets to optimize the circulation pattern and to minimize dead spots where algae can bloom. The recommended angle for jets is 45° downward.
A:The potential of algae is always present, so its appearance is an indicator of one or more pool water deficiencies. In some cases, the deficiency is obvious, other times you may need to review the basic checklist: •Is the pool equipment, pump, and filter operating properly? •Is the circulation pattern of the pool water minimizing dead spots? •Are the pH and Free Available Chlorine (FAC) in the recommended ranges?
