Hmmm... I didn't know that  (Algae)

This week I was browsing through some of the products on our shelfs and had a question about the algaecide we carry….Well that one question led to this research! Enjoy!!

           ALGAE!!! Prevention

Algae. Ick, right? Who would want to deal with that in their pool all summer long when they could be swimming! The problem is, by the time you can actually see this single celled microorganism there are literally millions of plants already in your pool! So, what is the very best way to eliminate the problem of algae? PREVENTION!!!

You should always have a good filter system and chlorinating system in place for your pool. Chlorine kills algae. Make sure to test your water frequently and keep your pH levels where they should be.  It’s good to have a vacuum and clean your pool regularly. Algaecide should be a normal chemical part of your pool maintenance routine. Nelson’s Hometowne Recreation offers all of the products and services needed to help you prevent algae!  Algaecide 30 is a great chemical to add to your cabinet!

           ALGAE!!! Treatment

Prevention didn’t go as well as you hoped and algae formed anyway? Treatment of an algae problem is much the same for all types of algae. You will need to first make sure your water is testing to the pH desired for your pool. (Bring me a sample!) Desired pH can range from 7.2 to 7.8. You should always brush the algae away from the sides, bottoms or cracks and crevices in the pool. This would be a great time to vacuum it up! If you find that it’s impossible to vacuum, use a flocculent. Next, you should shock your pool. It’s a good idea to check your filter and clean it or replace it at this time too. After all this is done, it is back to using the algaecide. Depending on the type of algae, you should use the Algaecide 60 or Concentrate Algae Kill.


         ALGAE!!! Whoa, what?! Different types?!?!

                Ok, so we know how to prevent and treat the algae, but we should also try to identify the stuff. There are 3 main types of algae that can form in your pool. Green algae is the most common and easiest to kill. This is the algae that is floating in your water, most likely turning it a horrible shade of green. Just follow the treatment! Mustard algae is yellow and looks like sand or dirt at the bottom of your pool. This one is chlorine resistant, so the Concentrate Algae Kill is the algaecide you will want to use. Also, check your pH and filter systems frequently after discovering mustard algae. Black algae is rare, but also the hardest algae to kill. It can look like tar and have a slimy feel to it. This algae sticks in cracks and crevices of pools. Vigorous brushing and vacuuming will help remove it, along with a strong algaecide.


So, this was my exploration on algae. I hope you enjoyed learning a few things. I always enjoy researching an unknown. If you want me to find an answer for you, I am always willing! E-mail me at jess@nelsonshtr.com or come on in to the store!
