Tips and advice

Crystal-clear, clean, and pleasant water starts with proper filtration. A sand filter is an essential piece of equipment to maintain the water quality of your pool throughout the swimming season. But it needs to be properly sized! This guide will help you choose the right sand filter based on the volume of your pool, whether it’s above-ground or in-ground. A correctly sized filter optimizes system efficiency, reduces maintenance, and ensures consistently enjoyable swimming. Why Is Filter Size Important? A filter that’s too small will constantly be overloaded, resulting in cloudy water, algae buildup, and premature wear on your system. On the other hand, a well-sized filter offers better filtration performance, reduces backwash frequency, and extends equipment life.
