My installation would be on big inground Spa (7ftX12ft) how do sand filters do with hot water only
Hi Kevin, This unit can operate without any issues as long as the water temperature does not exceed 104°F.
When should I change the sand in my filter?
You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.
