"One oven doesn't work at all ( my choice, see above), the "working" oven was never calibrated properly so using it is hit or miss. It's time to call American Home Shield to see about replacing the entire unit. I'm waiting to finish other home projects before calling them. I don't know if I'll request Greenway again."

Install Above Ground Pools questions, answered by experts

Calcium lumps in a pool are calcium deposits that form when a pool's water parameters are not in the normal range. They can float around on the surface of the pool water, making it look and feel dirty. The most common causes of calcium lumps in pools are calcium hardness above 1,000 ppm, alkalinity over 120, and a pH over 7.8. Keeping your pool’s calcium levels, alkalinity, and pH levels within the normal, safe ranges is the best way to prevent calcium lumps and other problems, including damage to the pool surface.

Before deciding to install a swimming pool in your yard, there are many factors to consider. Even if you still need to figure out the specifics with your pool installer, having an idea of what you'd like will help the initial consultation. Some topics to consider include:

  • Will you use salt water for your pool or traditional hose water?

  • How big of a pool do you want to install? How deep?

  • What special zoning laws do you need to follow for your area?

  • Do you want to keep it simple or add special features like underwater lighting and waterfalls?

Yes, it’s possible to DIY a plunge pool and shave labor costs off of the project total. If you’re considering a DIY build, keep in mind that you will be responsible for pool installation and landscaping (which may require excavation). This type of DIY project is best left to particularly handy homeowners who have prior pool installation experience. 

Figuring out how to clear a green pool can seem tricky at first, but it’s all about knowing which pool cleaning chemicals to use. You may think of using baking soda to help you with your algae problem, but unfortunately, it won’t help. This is because baking soda only raises your pH and alkalinity levels. 

Instead, you need to use pool shock to clear up a green pool—the shock raises the free chlorine levels and will kill the algae.

The generator in your saltwater pool conversion kit transforms sodium chloride—the same salt as table salt—into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.
