What are the different types of inground pool filtration systems available?

There are mainly three types of inground pool filtration systems available: sand filters, cartridge filters, and diatomaceous earth (DE) filters.

Sand filters are the most commonly used type of pool filtration system. They use a layer of sand to trap dirt and debris as water passes through it. Sand filters are easy to maintain, cost-effective, and can last for several years.

Cartridge filters are another type of pool filtration system that uses a cartridge made of polyester or other materials to trap dirt and debris. Cartridge filters require less water to clean than sand filters, and they can filter out smaller particles than sand filters.

Diatomaceous earth (DE) filters are the most effective type of pool filtration system. They use a fine powder made of fossilized diatoms to capture even the smallest particles in the water. DE filters need to be backwashed and recharged with new DE powder regularly, which can be time-consuming and expensive.

When choosing a pool filtration system, consider factors such as the size of your pool, the amount of debris in your area, and your budget. Each type of filtration system has its advantages and disadvantages, so it's essential to choose the right one for your needs.
