Pool Algaecide

Swimming Pool Care

With this knowledge you'll have the best information, maintenance, and tips using the proper swimming pool care, chemistry, and chemicals.

Pool algaecide is mostly widely used as a preventative measure, although I’ve had to use them when I walked into a backyard and the pool had that “walk across it” look.

If you have ever walked into your local pool supply store and have seen the rows and rows of algaecides, well, you may have become overwhelmed. Which one do I need? Which one works best for green algae?

Believe me, it can be difficult to decide which one is best for your situation.

Well, you’re here for information, and that’s what you’ll get. This comes from 10 years of experience with pools.

And the best part about being here, it’s free.

Swimming Pool Algae

1. Check your pool water chemistry and filtration system
   before using an algaecide. You may just need to balance the water to clear up your pool. Pay attention to the pH level. You'll want to get it down to about 7.0-7.2.
2. If you have an algae swimming pool, and you’ll know if you have one, find out which kind of algae you have. If it’s a green algae or yellow algae, then you may just need to shock you pool.

   If you have black or mustard algae, you may need a good pool algaecide as these types of algae are sometimes pool chlorine-resistant..

3. Adjust your pool water chemistry, be sure you have back-washed your sand filter or DE filter, then shock your pool. If you have a cartridge filter be sure to clean them out well. You may want to wait a day or so to allow the chlorine to do its job. If you still have the algae problem after a couple of days you may need a good pool algaecide for killing algae.

I suggest you go to your local pool supply store and not one of those mega-stores. The people who work at the pool store should know all about algaecides and what would work best for you.

Those big mega-stores are good for everyday basic pool care, but not when you have a swimming pool algae problem.

4. Get the best pool algaecide you can buy

Don’t skimp because you want to get rid of this problem quick, fast, and in a hurry.

I suggest buying an algaecide that has a “chelated copper” agent. This is great, unless your fill water is your well water. If you do have well water, there are many non-metallic pool algaecides that will work.

You may want to investigate a product called “Phosfree”. Phosphates are algae’s main food source. Kill the food source, kill the algae. Pretty simple.

Keep in mind that when algae dies, it’s releasing phosphates into the pool. This is why you really need to slam your algae problem with pool chlorine.

If you don’t, the next batch of algae may come back bigger and badder than the last. Don’t make your pool algae mad.

(Amount Needed to Reach 10 ppm)

Adding an extra 1-1 1/2 lbs. chlorine wouldn't hurt either. It's better to go a little higher than lower.

Remember the best pool algaecide in the world will not completely get rid of your algae issues. Algae in swimming pools is a common issue, but don't worry. You have lots of great information here.

Using the best pool tips, the best pool algaecide, and understanding your pool’s chemistry is the best way to keep that algae pool far from you.

Happy Swimming
