As a gardening and landscaping expert, I understand the importance of maintaining a clean and efficient pool filter. When it comes to DE (diatomaceous earth) filters, adding more DE after backwashing is indeed necessary to ensure optimal filtration.
After backwashing the DE filter, it is essential to replenish the DE that was removed during the cleaning process. The amount of DE to add will depend on the size and specifications of your particular filter. It is recommended to follow the manufacturer’s guidelines for the correct amount of DE to use.
To prevent DE from returning to the pool, it is crucial to carefully add the DE to the filter. One effective way to do this is by mixing the DE with water to create a slurry-like consistency. This slurry can then be poured into the skimmer, allowing it to distribute evenly throughout the filter.
However, it is not uncommon for some DE to find its way back into the pool, especially during the initial stages of filtration after backwashing. If you notice any DE particles in the pool, it is important to address this issue promptly.
To remove the DE from the pool, it is recommended to vacuum it to waste. This means bypassing the filter system and directly sending the pool water containing DE particles out of the pool. Once the DE has settled, you can use a pool vacuum equipped with a waste setting to remove it effectively.
It is worth mentioning that the amount of DE needed to be added after each backwash may vary over time. Factors such as the pool usage, water quality, and environmental conditions can influence the rate at which DE is consumed. Therefore, it is a good practice to monitor the effectiveness of your filtration system and adjust the amount of DE added accordingly.
As a personal experience, I have encountered situations where there was an excessive amount of DE returning to the pool even after following the recommended guidelines. In such cases, reducing the amount of DE added during the next backwash and recoating can help mitigate this issue. It is generally suggested to decrease the amount by 1 pound to find the right balance between filtration efficiency and minimizing DE particles in the pool.
Adding more DE after backwashing is necessary to maintain the effectiveness of your DE filter. By following the manufacturer’s recommendations and adjusting the amount as needed, you can ensure efficient filtration and a clean pool. Remember to address any DE particles in the pool promptly by vacuuming to waste for optimal pool maintenance.
