How To Clear Up Green Swimming Pool Water

You need to jump on it quick, fast, and in a hurry because the longer you wait to more chance the pool algae will stain your swimming pool and cost you even more time and money.

That's something we could all use more of.

The Best Way To Clear Up And Remove Swimming Pool Algae

When you walk outside and see green pool water, well, that's never fun, especially when it’s a major weekend and you have all of your friends over.

If you see a green swimming pool, you must take immediate action in killing the algae. Doing this will lessen the risk of staining and will lengthen the pool water life. There's much information out there in internet land concerning how to get rid of your green pool water and killing swimming pool algae.

Many sites will tell you the proper amount of pool chlorine you'll need, an algaecide, and this and that. They all have a grain of truth to them.

But I'm going to tell you, free of charge, the best way, and the reasons, to get rid of your green swimming pool algae problem:

First you should:

But wait!! You've read on this site to keep your pH level at 7.6-7.8. What is the deal with 7.0-7.2? Well, glad you asked, and here it goes.

I suggest you use granular chlorine, a.k.a. Calcium Hypochlorite, to shock your pool. This kind of pool chlorine has a pH level of 12.

Now, anything over the pH level of 8.0 and you're only using about 25% of the chlorine, which means, you've lost 75% of the active swimming pool chlorine. When you add your pool chlorine, your pH will automatically go up, so get that pH down!! If you start the pH a bit lower, you're using more active chlorine than you would if your starting pH was a bit higher.

See, very simple.

Also keep in mind when you use Calcium Hypochlorite, you may get cloudy pool water. This is normal and will clear up with proper filtration.

You want to get rid of the dead algae.

You’ll notice this is starting to eliminate the swimming pool algae when your water turns from a green to white or grayish. Also, there will be dead swimming pool algae on the bottom of the pool. This can be filtered out through vacuuming the bottom of the pool. Keep brushing and vacuuming to rid the pool and any residual algae and remember to keep filtering and backwashing to get rid of the swimming pool algae. If you have a DE pool filter, you'll need to re-coat or recharge the grids with each backwash.

If you have cartridge filter remember to take the filter out and clean it two (2)times per day with a regular garden hose, never a power washer. Brush and filter then brush and filter and then after you do those it’s time to brush and filter some more.

Remember, when you have a swimming pool algae problem, there is no quick fix. It will take time, effort, and patience to clear up your pool.

When your swimming pool chlorine is down to 1.0ppm-3.0ppm the pool will be safe to swim in once again.

Obviously you would NEVER allow anyone to swim in the pool until the swimming pool algae is gone and the water has cleared up.

How Much Pool Chlorine To Clear Up Swimming Pool Algae?

You know that smart people ask the right questions. So here's the answer to that question:

1. Take the number of gallons in the pool and multiply by 8.34. This tells you how many pounds of water are in the pool.
2. Take the number 1,000,000 (a million) and divide it by the answer you have from your first calculation. This will tell you how many parts per million that 1 pound of chemicals will be present in your pool.
3. Take the number 10 and divide it by the answer you got after the second calculation. This tells you how many pounds of chlorine you will need to add to get 10 ppm.

Example #1

Here's an example with a 15,000-gallon pool:

Example #2

Here's an 18,000-gallon pool:

Remember once again, don't skimp and try to save a few pennies on the pool chlorine. Your green swimming pool will like it if you don't use enough. I suggest you get these calculations and then add another 1/2 pound of swimming pool chlorine, just to be sure. Don't be scared of swimming pool algae because it's not scared of you.

Or, you can simply go to the swimming pool chlorine and this will give you the chart you need to shock or super-chlorinate your swimming pool.

If you want to bring the pool chlorine level up 20-25ppm, then just double the amount of pool chlorine.

Drop that pool chlorine hammer, scrub, and backwash to get rid of that awful green swimming pool. Water mold can be just as frustrating.

It will take a little blood, sweat, and tears, to clear up swimming pool algae, but don't worry. You're not the first person to have swimming pool algae.

Avoiding is the first step.

Just follow these great pool tips and you'll be fine.
