It takes more electricity to run one, so it’s not necessarily cheaper to run a salt water pool. However, the cost difference is relatively minor; it may cost an extra $50 over the course of a year. However, salt costs a lot less than chlorine sanitizers. This lowers the overall maintenance costs for a salt water pool compared to chlorine pools.

Yes, you will need to shock your pool with high levels of chlorine or bromine when you first fill it to kill off bacteria and pathogens. You’ll need to wait for the chlorine concentration to come back down to a safe level before swimming. After that, you can test and maintain the chlorine and other levels as normal. The only exception to this is if you get pool water delivered by a professional. In that case, the water might come pretreated, so you might not need to shock it.

Yes, you will need building permits for an inground pool, and your pool installation company should pull them for you. The permit filing fee will usually sit between $400 and $1,800, and it should appear on your contract or invoice. You may want to confirm with your contractor that they will pull all necessary permits. You might also need a permit for a new fence, as many municipalities have special fencing requirements for properties with pools. A fence permit costs between $50 and $500. This expense may not be included in your pool installation estimate.

You can place many materials under a pool to level it, including sand, concrete, solid foam, pavers, or finely crushed gravel. You can also use a tamper or roller to level ground without using a shovel to dig. No matter the material, make sure to level the ground with sand first for a smooth, even surface for the pool to sit on.
