There are many factors to consider when building an in-ground concrete pool. This includes the pool’s primary purpose (relaxation or exercise) if you live in a warm or cold climate (how often it’ll be used), and if you have the budget for chemical treatments and pool maintenance. In-ground pools are often more costly than aboveground pools, but they’re considered more luxurious and hold more value.

The best way to kill off an algae bloom in an aboveground pool is to shock it with a large dose of chlorine. Shock typically kills off algae in about one to three days, although it can take longer if the pool water is in poor condition. After the shock treatment, add algaecide to prevent algae from growing back, and test the water every few days with test strips to ensure the pool’s pH doesn’t get out of whack.

The disadvantages of container pools come down to flexibility and customization. Shipping containers come in standard sizes, so the sizes and shapes are limited. They also have a very distinctive look, which may not suit the aesthetic of your backyard. 

Beyond that, while container pools are more affordable than in-ground pools, certain models can be more expensive. This includes the cost to heat your pool, since the metal walls have more heat transfer than other types of pools (which some brands circumvent with insulation).

Installing a pool chiller can give you more control over the temperature of your pool, especially if you live in a climate with hot summers. Just a few degrees of cooling can make your swim feel more refreshing and allow you to use fewer pool chemicals by slowing down the growth of algae. You might not need a pool chiller if you live in a climate in which temperatures tend to dip at night.
