How To Clean A Green Pool

Pools are an inviting place to cool off and relax, but these standing bodies of water can invite algae. If your pool grows green and cloudy, you'll need to invest in chemicals and tools to clear up the algae, and then test the water regularly.

In this guide you will learn how to fix a green pool, including tools and suggestions, so that you and your family can enjoy it all summer long!​

How To Clean A Green Pool Fast

To kill the algae in your pool, you can shock the pool system with a high dose of chlorine and algaecide. You'll want to avoid the water for 24 hours or as directed, then clean the pool by filtering the water thoroughly and scrubbing the sides and bottom.

Tools

Filters are generally reusable; you'll need to check your system and refer to the owner's manual to make sure you're cleaning your filter properly.

Clean filters are critical to maintain a clean pool.

Pool Cleaning Robots are available for solid surface or vinyl pool liners. One of the challenges to cleaning up algae overgrowth with filters alone is to get the algae off the bottom of the pool.

A pool bot does a great job of churning the water so the filters can do their work.​

Chemicals

A healthy pool pH runs between 7.2 and 7.8. To shock the pool, you will have to take it out of the healthy range, which will make it inhospitable to any and all creatures that may enjoy it.

Preventing Algae Growth

Regular maintenance is critical to make sure algae doesn't get a foothold.

There are 3 maintenance items to enjoy a clear pool:

  • Clean Filters
  • Algaecide Treatments
  • Scrubbing & Skimming

If your pool doesn't get a lot of use, investing in an automatic pool robot may be a good idea.

These tools will happily run all over the bottom of your pool, vacuuming up water from the bottom, filtering out algae and debris, and churning the water high enough for your filtration system to catch and cycle it again.

Not every bot will work in every pool, so you'll need to do some research to buy the best robotic pool cleaner for your water volume and pool surface.​

A weekly treatment with algaecide is recommended if climactic conditions in your area are particularly humid.

Additionally, regular testing of the water for a proper pH level is critical.

Ideally, regular testing, chlorine adjustments and algaecide will protect you from needing to shock (and thus have to avoid) your pool, but algae is insidious.

Once you can see it in the water, you have a severe case of algae overgrowth, so it's best to rely on your testing strips.

Finally, make sure your filter system is properly sized for your pool and get into a regular pool filter cleaning schedule. Your filters can't work if they're clogged.

A regular skimming habit will also reduce the load on your filters. Keeping the water moving and well-filtered will reduce the need to know how to clean a green pool.

Final Thoughts For When Your Pool Is Green and Cloudy

Algae overgrowth will tint the water, but it really causes havoc when it settles on the sides and bottom of your pool. Algae thrive in humid conditions and will happily grow in water that isn't moving.

To keep your pool algae free, it's important to keep your pool free of debris such as leaves. These solid particles will clog your filtering system and make it harder to keep the water moving.

The slimy coating on algae will also clog up your filters, so maintaining a cleaning schedule to clear them is critical.

A pool is a great way to exercise in the heat and enjoy the warm weather in cool comfort. With proper maintenance, a little scrubbing and some help from chemistry, you can enjoy crystal clear, algae-free water!​
