During which phase of the filter cycle is body feeding (DE) conducted?

Body feeding, specifically with diatomaceous earth (DE), is conducted during the filter cycle to maintain the efficiency and performance of the filtration system. When the filter is in operation, adding DE helps to coat the filter media, increasing the filtration capability and improving water clarity. This procedure ensures that the filter operates effectively by enhancing its ability to trap particulates and impurities present in the water.

In contrast, conducting body feeding at the beginning of the cycle would not provide immediate benefits since the filter media needs to be in operation to effectively capture and retain the DE. Performing this action at the end of the cycle or after backwashing would be counterproductive, as backwashing is meant to clean the filter and remove trapped debris. Therefore, body feeding during the filter cycle is essential for optimal filtration performance and water quality maintenance.
