What should you do if added chemicals to get rid of algae in your swimming pool but now it has white foam floating on top can i add more algeacide or will that make matters worse?

Do not add more algaecide. Adding more algaecide will not help to get rid of the white foam and may actually make the situation worse.

The white foam is likely caused by a reaction between the algaecide and the dirt and debris in your pool water. When algaecide is added to pool water, it kills the algae cells and causes them to release their contents into the water. This can include things like chlorophyll, proteins, and carbohydrates. These substances can then react with the dirt and debris in the water to form a white foam.

To get rid of the white foam, you will need to remove the dirt and debris from your pool water. This can be done by vacuuming the pool and then using a pool filter. Once the dirt and debris have been removed, the white foam should go away.

If the white foam persists, you may need to shock your pool. Shocking a pool involves adding a large amount of chlorine to the water in order to kill any remaining algae cells. This will also help to remove any residual algaecide that may be in the water.

Once you have shocked the pool, you will need to wait at least 24 hours before swimming. This will give the chlorine time to dissipate and the pool water to return to a safe level for swimming.
