Generally, you should run your pool pump for eight to 12 hours a day to keep your water clean and chemical levels balanced. The ideal runtime can vary depending on your specific pump type. While running the pump as much as possible is ideal for cleanliness, it can increase electricity costs. To save money, you can run the pump strategically during non-peak hours when electricity is cheaper, which is often in the evenings or at night. The hours do not need to be consecutive.

The best way to dissolve algae is to use pool shock. The shock increases the free chlorine levels in your pool, which in turn kills bacteria, microorganisms, and algae. You can opt for granulated shock that you mix with water or a premixed liquid shock.

Keep in mind that using pool shock is just one of the steps you need to take to get rid of algae from your pool. Unless you also brush, vacuum, and clean the filter, your algae problem may return.

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.

Technically, you can fill in a pool yourself—with the caveat that filling in a pool requires the ability to drain the pool properly and move a substantial amount of dirt, which aren’t beginner DIY skills. If you want to fill in a pool, you’re better off hiring a local pool removal professional.
