Are 30 ml pool liners sufficiently better than 20 for the price difference?

Pool liners are typically measured in mils (thousandths of an inch), not milliliters (mL). The thickness of a pool liner is an important factor in determining its durability and longevity. Thicker liners are generally more resistant to punctures and tears, and they can withstand the effects of UV radiation and chemicals better than thinner liners.

30 mil pool liners are typically thicker and more durable than 20 mil pool liners. This means they may last longer and require less maintenance, which can save you money in the long run. However, 30 mil liners are also more expensive than 20 mil liners, so you'll need to decide if the extra cost is worth it for your needs.

Here are some things to consider when choosing between a 30 mil and 20 mil pool liner:

* The size and shape of your pool: Larger pools and pools with complex shapes require thicker liners.

* The climate in your area: If you live in an area with extreme weather conditions, a thicker liner is a good investment.

* Your budget: 30 mil liners are more expensive than 20 mil liners, so you'll need to decide how much you're willing to spend.

Ultimately, the best way to decide which pool liner is right for you is to talk to a pool professional. They can assess your specific needs and help you choose the best liner for your pool.
