Why would you have sediment at the bottom of your pool even after run DE filter and use Bacqaucil?

1. Filter Issues

- Faulty or clogged filter: If your DE filter is not functioning properly or is clogged, it may not be able to effectively remove sediment from the water. Ensure the filter is clean, properly maintained, and operating correctly.

- Filter media: The DE filter might require more or new DE powder. Ensure you have added the correct amount of diatomaceous earth (DE) powder to your filter according to the manufacturer's instructions. Also, check if it's been too long since you last changed the DE powder.

2. Pool Chemicals

- Improper chemical balance: Incorrect pH levels, insufficient chlorine, or unbalanced water chemistry can contribute to the formation of sediment. Test the pool water regularly and adjust chemical levels as needed to ensure the water is properly balanced.

- Clarifying agents: Some clarifying agents, while designed to clear up cloudy water, can sometimes leave behind sediment. Follow the product instructions carefully and consider trying a different clarifying agent or flocculent if you notice persistent sediment.

- Metal precipitation: If your water has high levels of dissolved metals, such as copper or iron, they can react with pool chemicals and form insoluble compounds that can settle to the bottom as sediment. Use metal sequestering products or controllers to prevent metal precipitation.

3. Bather-related

- Sunscreen and cosmetics: Sunscreens, lotions, and other personal care products can leave residues that contribute to sediment buildup in the pool. Encourage bathers to rinse off thoroughly before getting in the pool and avoid excessive use of such products.

4. Debris

- Fine debris: Even if your pool is covered, tiny particles of dust, dirt, and other debris can still find their way into the water and sink to the bottom. Regular cleaning and vacuuming of the pool are essential to remove this type of sediment.

5. Structural Issues

- Pool finish deterioration: Over time, the pool plaster or lining may start to deteriorate, releasing particles that accumulate as sediment. If this is suspected, consult with a pool professional to assess the condition of the pool finish.

6. External factors

- Environment: If your pool is located in a dusty or windy area, fine particles from the surrounding environment can be blown into the water, contributing to sediment over time.

_Regular maintenance, proper pool chemical management, vacuuming, and addressing any underlying issues_ will help minimize sediment buildup and keep your pool water clean and clear.
