You should avoid filling your pool overnight—just as a precaution. You’ll want someone around to check on the progress. If your hose springs a leak or you overfill your pool, you could end up with some costly water damage. At worst, you could flood your home’s foundation. For this reason, ensure someone is home and awake, even if your pool takes a couple of days to fill.

Figuring out how to clear a green pool can seem tricky at first, but it’s all about knowing which pool cleaning chemicals to use. You may think of using baking soda to help you with your algae problem, but unfortunately, it won’t help. This is because baking soda only raises your pH and alkalinity levels. 

Instead, you need to use pool shock to clear up a green pool—the shock raises the free chlorine levels and will kill the algae.

The type of sand you need for your sand filter depends on the manufacturer’s instructions, but you’ll need to use sand specifically for pool filters. Silica sand is a wallet-friendly, common choice that’s relatively easy to replace. You’ll choose between various grades of sand and different-sized sand grains.

The average 12-by-24-foot in-ground pool costs $48,500, but depending on the features and materials, prices can trend even higher. You’ll spend less on a rectangular vinyl or fiberglass pool than on a concrete pool in an elevated style (think infinity pool or lagoon pool). Added features like heating, lighting, diving boards, or decking will increase your overall cost.
