It's not ideal, and if your pool’s pH is seriously low (below 7), swimming can be dangerous until you raise it, potentially causing severe irritation and damage to the skin and eyes.

Keep in mind that low pH can also be responsible for damaging the pool itself. Acidic water can contribute to the cracking of your pool's liner, which may cost up to $2,500 to replace, making this an expensive fix.

Pool chemical levels should include a pH between 7.4 and 7.6, alkalinity between 80 to 120 ppm, and chlorine from 1 to 3 ppm. The size and type of your pool determine additional chemical levels, such as stabilizers and pool shock, but you can get to know these numbers using our pool maintenance 101 guide.

Setting up a pool on unlevel ground is not recommended as it can damage the pool or yard and put the safety of those using it at risk. If a pool isn't level, the water's weight won't distribute evenly, putting excessive pressure on certain parts. This can cause the pool liner to tear or the walls to collapse, leading to water damage, expensive repairs, or potential injury to swimmers. It is more cost-effective to level the ground correctly before installation rather than waiting to address serious structural issues later.

The best way to find a reliable pool service company is to look for one that is properly licensed and insured, has positive customer reviews, maintains good ratings with the Better Business Bureau (BBB), and provides pricing that fits into your budget. You can also ask the following questions to see if a pool service company is right for you:

• Do you provide discounts if I sign up for multiple services or a contract?

• What services can you provide?

• How many years of experience do you have?

• Do you have any customer references I can call?
