How long should I run my Pool Filter Pump? As the weather here in Houston heats up, you should be running your pool filter pump accordingly. We suggest running the pool filter pump 8 – 12 hours per day depending on the size of your pool, amount of landscaping around the pool and the level of usage during the summer months. With warmer weather, the water needs to be circulated and filtered longer due to higher swimmer usage (kids on Summer break) and to prevent algae blooms. Now is also the time to make sure your pool filter is cleaned and ready for the kids this summer. Contact your Houston Pool Service Department to schedule your pool filter cleaning today.
