Brown Algae Production & Swimming Pool Algae Control. Understand Types Of Algae In Water & Algae Facts .
The bad news is you have brown algae in your pool. It clings to the pool surface and is one of the more difficult types of algae to get rid of. Believe it or not, brown algae is a strain of yellow or mustard algae. It's not all that common, but can creep into your life when you least expect it. It can normally be found in shaded areas that get little sun, again, very similar to yellow algae. This is a very ugly kind of algae that will make your pool very uninviting, especially when you have a big party the next day. Killing it takes a little time, energy, and effort.
Pool algae problems are normally a direct result of poor swimming pool water chemistry, pool water maintenance and/or bad filtration. Weekly pool maintenance is needed or else you will get a host of water problems.
Steps should be taken to ensure you won't have more swimming pool problems such as:
Having your swimming pool chlorine, pool alkalinity, pH, CYA/pool stabilizer, and calcium hardness adjusted correctly is very important.
If you have algae, you must take immediate action in killing it. Doing this will lessen the risk of staining and will lengthen the pool water life.
First You Should:
Brush your pool with a wire brush and, if the water is clear enough, vacuum to WASTE. If you have a cartridge filter, make sure it's clean. Purchase a high quality leaf rake, (not those simple blue square skimmers) and scoop out as much debris from the bottom and top of the pool as you can. If you're able, make sure the bottom drain is clear and free from debris. Keep an eye on the pool's water level and maintain that between 1/3 - 1/2 from the bottom of the skimmer.
Bring the pH, alkalinity, CYA, and hardness in line
You want to maintain a high chlorine level up to 15 - 17 ppm. Add chlorine morning and night.
Backwash or clean your filter at least once per day
Use a pool algaecide (PolyQuat 60) and follow the instructions on the container. This is for preventative maintenance for recurring algae while the chlorine is busy killing the algae. Algaecides won't kill already existing algae. Don't use a copper algaecide as this will add metal to the pool. And don't add a flocculant. This doesn't address the algae problem. Save your money.
The water will turn from a brown to white or grayish. Also, there will be dead algae on the bottom of the pool. This can be filtered out through your pool filter and vacuuming. Once the water has cleared and you lose only 1 - 2 ppm within a 12 hour period will you know the algae is dead.
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 around 3 - 5 ppm the pool will be safe to swim in once again. Don't allow anyone to swim in the pool until the brown algae is gone and the water has cleared up.
My friends, one of the WORST, and very expensive, pieces of advice you can hear is, "Oh, you have brown algae, or green pool water? Well, let me tell you how to clear it up. First is you need to get your pH and alkalinity in line, then shock the pool and add one bottle of phosphate remover. If that doesn't work, add a bottle of algaecide, let it run for 4 hours, and add a couple of tabs in the skimmer. If that doesn't work, add some Green Out, Yellow Out, 2 more bottles of phosphate remover and 1 bottle of clarifier."
Folks, that advice (if you can call it that) will absolutely cost you hundreds of dollars and TONS of frustration. That is NOT how to clear up brown algae or a cloudy pool but it is the best way to ruin your Summer and drain your wallet.
