# Pool opening

Pool opening is restarting a pool after it was closed or sat idle for a season.

Opening means removing covers, refilling the water, reconnecting equipment, and balancing the chemistry. A pool that sat idle often needs more than a simple restart.

Test the water before you swim. Check for equipment damage, especially after a freeze. A green or cloudy pool may need a deeper cleaning first. See [green pool cleanup](https://marinapool.multisites.ai/guides/green-pool-cleanup) for the steps. Take it slowly. Run the pump, check for leaks, and let the water circulate before you add large doses of chemicals. A fresh test a day later shows whether the balance holds.
