When you need gravity filtration, use the Hydro-Clear® pulsed-bed sand filtration system. It features a unique underdrain system and a shallow bed of mono-media, fine-grained sand, a design which permits the filter media to be “pulsed” periodically as solids build up.
What does this mean to you? Your filter runs are extended and the filter is automatically kept on-line, despite varying loads and changing water characteristics.
