Cleaning up a flooded pool needs to be done correctly to avoid damage to the pool equipment as well as the shell of the pool. Use this guide for removing mud, dust, clay, leaves and other organic/inorganic matter from a flooded pool.
Large amounts of dust and dirt can be brought in with the rain. This dirt causes a few issues for pools such as dirty water, chemical imbalances & high phosphate levels that can encourage algae growth, along with the additional water going into the pool and potential overflowing issues.
