A Guide to Clearing Algae Problems

A Guide to Clearing Algae Problems

Is your pool clouded with unsightly green algae? If your kids would rather head down to the nearest swamp to play “Marco Polo” than dive into your home pool, it’s time make a change. Here are some pool maintenance tips to clear your algae problem.

Clean Debris

Did you know that organic debris like leaves acts as a food source for algae? There’s no point trying to address an algae problem if your pool is basically a giant buffet table of food for algae. Use a cleaning net or vacuum to suck up the decomposing organic waste.

Adjust pH

Algae creates a vicious cycle. It causes your home pool’s pH level to rise, and higher pH levels promote the growth of algae. This is why we recommend using muriatic acid or Lo & Slo to adjust the pH back down to 7.2. Follow the instructions on the package and then wait three hours. Repeat this step if the pH is still too high.

Shock

Now is time to shock the pool. If you are trying to kill algae, a light or blended shock won’t cut it. Instead, use the instructed amount of Liquid Chlorine or HTH Extra. If your algae build up is really bad, double the dosage. Leave your pool cover off until the shock treatment clears up.

Algaecide

After an hour, add the recommended dose of Eclipse or Erase algaecide. Go right to the good stuff and don’t bother with weak “bulk” algaecides that won’t get the job done.

Brush the Pool

You didn’t think the pool chemicals would do all the work, did you? Brush the entirety of your pool to knock stubborn algae out of place and improve chlorine distribution. If you want to clear your algae problem, you need some elbow grease.

Circulate

A stagnant pool will just invite algae to start growing again, so you need to circulate. Otherwise, chlorine won’t reach the algae that has built up in your pump, filter, and pipes.

Repeat!

You need to repeat these steps daily (with the exception of algaecide) until the algae is killed off. It often requires two to five cycles, so be persistent and don’t skimp on any of the products.

Resistant?

If the algae still isn’t clearing up, come talk to us at the Purewater store. Your pool may have high phosphate levels, which means you need to add an agent like Phos-Free that removes phosphates.

Clear Dead Algae

Remember how we said organic debris becomes food for algae? Well dead algae is organic debris, so make sure you get rid of it quickly. Make sure to chemically clean your sand with Filter Brite to avoid more algae blooms.

Chlorine & pH Levels

Even after you’ve removed the algae, keep your chlorine levels at least 3 ppm and keep your pH between 7.2 and 7.4. Proper pool maintenance after you’ve cleared algae will help keep the problem from recurring.

Monthly Testing

Just because you’ve dealt with one algae problem doesn’t mean you’re in the clear. Bring in a sample of your water to the store every month to make sure all your levels are in good order and prevent another algae growth problem.

If you need any more assistance with pool maintenance or your algae problem still hasn’t cleared up, call or come into the Purewater store and we’d be happy to help restore your home pool to its original beauty. Happy swimming!
