Where to buy sand for a pool filter?

1. Pool supply stores: Pool supply stores are one of the most reliable places to buy pool filter sand. They usually carry various pool sand types, such as silica, glass, and filter sand, and can also provide advice on the best type for your pool.

2. Home improvement stores: Home improvement stores like Home Depot and Lowe's often have a selection of pool filter sand. They may carry fewer options than pool supply stores, but they may be more convenient for some people.

3. Online retailers: Various online retailers sell pool filter sand, including Amazon, Walmart, and pool supply websites. You can find a wide range of options and prices online, but be sure to check the shipping costs and read reviews before you buy.

4. Local quarries or landscaping supply companies: Some local quarries or landscaping supply companies may also sell pool filter sand. This can be a cost-effective option if you need a large amount of sand, but it may be more challenging to find the exact type of sand you need.

When buying pool filter sand, it's essential to choose the correct grade and size. The recommended grade for pool filters is usually #20 silica sand, which is roughly 0.45-0.55 mm in size. This will effectively filter dirt and debris without putting unnecessary strain on your filter system.

It's also essential to consider the amount of sand you need. The amount of sand required will depend on the size of your pool filter. You can typically find this information in the filter manual or by consulting with a pool professional.

Remember that pool sand tends to be heavy and can be challenging to transport. It's a good idea to have a plan for how you will transport the sand from the store to your home before purchasing.
